World's dumbest question at the host stand?

This is a story someone told me recently and it's so good I have to share it.

At a restaurant with a patio a couple has just come in the front door. They approach the host stand.

"Hi, table for two please," says the gentleman.

"Would you like to sit inside or outside?" is the host's pertinent inquiry.

"I dunno, is it hot outside?"

Host's reply, "I don't know, was it hot when you came in from outside two seconds ago?"
