Here’s another cartoon contributed by Nadeem Irfan Bukhari (previous one published in the blog of Friday, April 27, 2007). It reminded me of a couple of old jokes. Did you hear about the statistician who almost drowned in a lake averaging only 2 inches in depth? (Normally this joke leaves no chance of survival, but I wanted to be nice and leave some probability of this.) Perhaps this is the reason for the more positive outcome: How do you save a drowning statistician? Take your foot off his (or her) head.
