Three men were using the urinals in a public restroom in DC.
The first man finished relieving himself, zipped up, strolled to the sinks and proceeded to wash his hands, using plenty of soap and water and doing a splendidly thorough job.
As he was drying his hands (with lots of paper towels), he loftily announced to no one in particular "At Harvard, I learned to be clean and sanitary." 
The second gent zipped up, marched briskly to the sinks, and scrubbed his hands with much less soap and water than the first man, doing a splendidly thorough job nonetheless.
As he was drying his hands (with only one paper towel), he severely announced to no one in particular, "At Yale, I learned to be clean and sanitary, but I ALSO learned to be thrifty and environmentally conscious." 
The third man finished relieving himself, zipped up, and ambled past the sinks to the door, muttering to himself, "In kindergarten, I learned not to рiss on my hands."
A man was walking along a California beach and stumbled across an old lamp. He picked it up and rubbed it and out popped a genie.
The genie said, "OK. You released me from the lamp, blah blah blah. This is the fourth time this month and I'm getting a little sick of these wishes so you can forget about three. You only get one wish!"
The man sat and thought about it for a while and said, "I've always wanted to go to Hawaii but I'm scared to fly and I get very seasick. Could you build me a bridge to Hawaii so I can drive over there to visit?"
The genie laughed and said, "That's impossible. Think of the logistics of that! How would the supports ever reach the bottom of the Pacific? Think of how much concrete... how much steel!! No, think of another
wish."
The man said OK and tried to think of a really good wish.
Finally, he said, "I've been married and divorced four times. My wives always said that I don't care and that I'm insensitive. So, I wish that I could understand women....know how they feel inside and what they're thinking when they give me the silent treatment... know why they're crying, know what they really want when they say 'nothing'... know how to make them truly happy...."
The genie asked, "Do you want that bridge two lanes or four?"
