How many lawyers does it take to change a light bulb?
Such number as may be deemed necessary to perform the stated task in a timely and efficient manner within the strictures of the following agreement:
Whereas the party of the first part, also known as "The Lawyer", and the party of the second part, also known as "The Light Bulb", do hereby and forthwith agree to a transaction wherein the party of the second part (Light Bulb) shall be removed from the current position as a result of failure to perform previously agreed upon duties, i. E., the lighting, elucidation, and otherwise illumination of the area ranging from the front (north) door, through the entry way, terminating at an area just inside the primary living area, demarcated by the beginning of the carpet, any spillover illumination being at the option of the party of the second part (Light Bulb) and not required by the aforementioned agreement between the parties. The aforementioned removal transaction shall include, but not be limited to, the following steps:
1.) The party of the first part (Lawyer) shall, with or without elevation at his option, by means of a chair, stepstool, ladder or any other means of elevation, grasp the party of the second part (Light Bulb) and rotate the party of the second part (Light Bulb) in a counter-clockwise direction, said direction being non-negotiable. Said grasping and rotation of the party of the second part (Light Bulb) shall be undertaken by the party of the first part (Lawyer) with every possible caution by the party of the first part (Lawyer) to maintain the structural integrity of the party of the second part (Light Bulb), notwithstanding the aforementioned failure of the party of the second part (Light Bulb) to perform the aforementioned customary and agreed upon duties. The foregoing notwithstanding, however, both parties stipulate that structural failure of the party of the second part (Light Bulb) may be incidental to the aforementioned failure to perform and in such case the party of the first part (Lawyer) shall be held blameless for such structural failure insofar as this agreement is concerned so long as the non-negotiable directional codicil (counter-clockwise) is observed by the party of the first part (Lawyer) throughout.
2.) Upon reaching a point where the party of the second part (Light Bulb) becomes separated from the party of the third part ("Receptacle"), the party of the first part (Lawyer) shall have the option of disposing of the party of the second part (Light Bulb) in a manner consistent with all applicable state, local and federal statutes.
3.) Once separation and disposal have been achieved, the party of the first part (Lawyer) shall have the option of beginning installation of the party of the fourth part("New Light Bulb"). This installation shall occur in a manner consistent with the reverse of the procedures described in step one of this selfsame document, being careful to note that the rotation should occur in a clockwise direction, said direction also being non-negotiable.
NOTE: The above described steps may be performed, at the option of the party of the first part (Lawyer), by said party of the first part (Lawyer), by his heirs and assigns, or by any and all persons authorized by him to do so, the objective being to produce a level of illumination in the immediate vicinity of the aforementioned front (north) door consistent with maximization of ingress and revenue for the party of the fifth part, also known as "The Firm".

How many people at a chess tournament does it take to change a lightbulb ?
Nine. One to complain about the lighting levels, one to say he thinks the lighting is OK, one to suggest someone calls the arbiter, one to go and call the arbiter, one to reminisce about lighting levels at the 1947 tournament at Hastings, one to complain about the disturbance the others are causing, both arbiters, and one to say he thought the lighting was better before they changed the lightbulb.
How many people at a chess tournament does it take to change a lightbulb?
Here is the current state of research... You need one to complain about the lighting. A second will say he thinks the light is fine. A third suggests the tournament director be called, and number four fetches him. An aged player (5) reminisces about the lighting levels at Nottingham 1936. The director (6) can't be found, but his deputy (7) arrives. Player eight says that if they increase the lighting levels it will reflect into his eyes. Number nine says they should have fluorescent lighting. Player ten says it's just a question of replacing the dead lightbulb, but player 11 thinks the bulb hasn't been working properly since the tournament began. The deputy arbiter asks an assistant arbiter (12) to make up a sign :
'Bulb defective.' A democrat (13) suggests taking a vote on whether to change the bulb and a businessman (14) forms the lightbulb changing association (LCA) as a pressure group to argue for better lighting. The world champion (15) is elected chairman. The FIDE president (16) sets up a working party (17-20) to establish agreed lighting levels with the LCA. The LCA chairman then has a row with its other members about direct/indirect lighting, and storms off with his lawyer (21) to found the Association for Changing Lightbulbs (ACL). The challenger for the world title (22) suddenly says he will not play under FIDE lighting. Three sponsors (23-25) emerge to hold the FIDE (direct light), LCA (fluorescent) and ACL (reflected light) championships, but none can match the interest attracted by Fischer (26) playing Spassky (27) with the new Fischer lightbulb, whose incandescence increases the longer you think. The last sane player on earth (28) sneaks into the playing room to change the defective bulb, but his replacement has the wrong fitting. His scream of anguish reveals him, and he is expelled from world chess for creating a disturbance.
