Bob the builder goes up to a girl in a nightclub.
He says, "I have an 8 inch ♥♥♥♥ and can shag all night"... After a few beers she takes Bob home with her.

The next morning she says,"You said you had an 8 inch ♥♥♥♥ and could last all night. Instead you have a 5 inch ♥♥♥♥ and lasted 3 minutes"..

Bob replies "I'm a builder love. It was an estimate"
