A “study”:http://news.bbc.co.uk/2/hi/health/6897023.stm by Washington University at St. Louis showed that old people find it difficult to “get” what’s funny. The study had undergrads and AARP-ers attempt to complete jokes and cartoon strips by picking the correct punchline from a group of options. From BBC News Online:
One such joke in the test was: “A businessman is riding the subway after a hard day at the office. A young man sits down next to him and says, ‘Call me a doctor, call me a doctor’. The businessman asks, ‘What’s the matter, are you sick?’.
The participants were expected to correctly identify the punch line as: “The young man says, ‘I just graduated from medical school’.”
Huh. Judging from the jokes my parents email me nonstop, I always thought this kind of humor was _only_ understood by old people.
