A man seeks medical help because he has a tapeworm. “Come back tomorrow with two bananas and a Snickers bar,” advises the doctor. The patient is perplexed, but he does what he is told.
He returns the next day with two bananas and a Snickers bar. The doctor then inserts both bananas and the Snickers bar up the man’s behind.
The doctor then instructs him to return the next day with two bananas and a Snickers bar. The man is puzzled, but he does as he is told.
This method is repeated by the patient and the doctor for 5 days. On the sixth day, the doctor instructs the patient, “Bring two bananas tomorrow, but instead of a Snickers bar, bring a mallet.” The patient is once again perplexed, but he complies.
The next day, the doctor inserts both bananas into the man’s buttocks before hastily grabbing the mallet and waiting.
All of the sudden, the tapeworm pops out saying, “Hey! Where’s my snickers bar?”
