Crazy Math

A psychiatrist is interviewing 3 guys in a nuthouse… he asks the first one, "What's 9 x 9?"

The guy thought about it for a while, then said "Thursday."

He went to the next guy, "What's 9 x 9?"

The guy thought about it for a while, then said, "156"

He went to the third guy, "What's 9 x 9?"

Very quickly the guy said, "81!"

The doc said, "That was very good… but how did you do it so fast?"

"Simple," the guy says, "I just subtracted Thursday from 156."
