A man walks in to the country store and asks the clerk for a package of condoms. The clerk asks “what size are you?”
“I dunno” replies the man.
Well the clerk tells him to go out back where there is a plywood fence with numbered holes in it. He is told to stick it in various holes to determine his size.
Well, this big ‘ol fat girl sees the man heading out back and runs around behind the fence. As soon as the man sticks it thru the hole, the fat girl picks up her moo-moo and backs up to the fence. A while later the man returns and the clerk asks him “Well, what size will it be?”
“Forget the rubbers,” the man replies, “I’ll just take 3 sheets of that plywood!”
