Ha, ha, I never get tired of that joke.
How does a differential topologist visualize 96-dimensional smooth manifolds? He first visualizes N-dimensional smooth manifolds where N is greater than or equal to some sufficiently large number. Next, he does a calculation on the side to confirm that 96 is sufficiently large, for the purposes of the present discussion. Then he substitutes 96 for N.
Theorem. A cat has nine tails. Proof. No cat has eight tails. Since one cat has one more tail than no cat, it must have nine tails.

A statistician is a person who thinks he's average because he has one testicle and one ovary.
What is the difference between a Psychotic, a Neurotic and a mathematician? A Psychotic believes that 2+2=5. A Neurotic knows that 2+2=4, but it kills him. A mathematician doesn't care what 2+2 is, so long as 2 and + are well-defined and the axioms determine the value of the operation.
How much does Technorati suck? Let S be the set of all ways that Technorati sucks. If I remove any one element of S, the remaining set can be placed in one-to-one correspondence with the original set S. That's how much Technorati sucks.
