A blonde and a brunette are walking downtown when the brunette sees her boyfriend in a flower shop. "Just great," the brunette complained to the blonde, "my boyfriend is in the flower shop buying me some flowers." The blonde responds, "Why is that a problem?" The brunette replies, "Because now he'll expect me to spend all weekend with my legs spread and my feet up in the air." "Why?" asked the blonde, "Don't you have a vase?"
