Two girlfriends - a blonde and a brunette - meet downtown for lunch. As they walk out of the restaurant, the brunette spots her boyfriend across the street leaving the floral shop with a large bouquet of flowers. "Oh, no! Not flowers again from Tom," she exclaims.
"What's wrong," asks the blonde, "don't you enjoy receiving flowers?" to which she replies, "Yes, but I don't feel like spending the next three days flat on my back, naked, with my feet in the air."
Blondie thinks for a second, then replies, "Don't you have a vase?"
