Comedian's IQ

I'm fairly sure almost all comedy is based on background assumptions people have for stupid reasons.

Not necessarily - all a joke needs to do with regard to assumptions is violate one; it doesn't need to be an assumption held for a stupid reason.

For example, one of my favorite jokes, one that Redd Foxx used to tell:
"Two women are walking down the street, and one woman nudges the other and says 'Hey look, is that your husband coming out of the florist's? He's got a dozen roses!'
The other woman grumbles and says "Yeah...Damn, I'm gonna have to keep my legs up in the air three days for this."
And the first woman pauses for a beat and says "Why don't you just get a vase?"'

Is the assumption that makes that joke funny a stupid one to have?
