A blonde and a brunette are sitting on a park bench talking about their horrible boyfriends when the brunettes boyfriend walks past and hands her a dozen red long stem roses. When he is gone the brunette turns to the blonde, sighs, and says "I can't stand him! Now he is going to expect me to stand on my head all night with my legs spread apart!" Then the blonde looks at the brunette with a confused expression and says "Why? Dont you have a vase?"
