A blonde and a brunette are walking down the street and pass a flower shop where the brunette happens to see her boyfriend buying flowers. She sighs and says, "Oh, crap, my boyfriend is buying me flowers again.....for no reason."
The blonde looks quizzically at her and says, "What's the big deal, don't you like getting flowers?"

The brunette says, "Oh sure.....but he always has expectations after getting me flowers, and I just don't feel like spending the next three days on my back with my legs in the air."

The blonde says, "Don't you have a vase?"
