Two friends, a blonde and a redhead, are walking down the street and pass a flower shop where the redhead sees her boyfriend buying her flowers.

The Redhead sighs and says: "Oh poo, my boyfriend is buying me flowers again."

The blonde looks quizzically at her and says: "You don't like getting flowers from your boyfriend?"

The redhead replies: "I love getting flowers, but he always has expectations after giving 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?"
