f(x) goes into a bar and asks for a drink. "I'm sorry," the barman says. "We don't cater for functions."
Statistics are a lot like mini-skirts. They can look great but what they cover up is more important then what they reveal.
Two statisticians are out hunting, taking aim at a deer. The first statistician shoots, it's a good shot, but he misses by 5 foot to the left. Cursing his luck he fires again, only this time to miss by 5 foot to the right. Suddenly the second statistician starts jumping up and down shouting, "We hit it! We hit it!"
And the deer, of course, waited for the second shot.
