"It was just before an early morning meeting, and I
was really trying 
to get to the bagels, but I couldn't help overhearing
a conversation between one of my statistical
colleagues and a surgeon.

Surgeon: "Yes, I used multinomial logistic

Statistician: "Really? How did you come up with that?"

Surgeon: "Well, I tried each analysis on the SPSS
drop-down menus, and that was the one that gave the
smallest P value"."
