A beautiful chesty blonde steps on the bus and there is nowhere to sit.  She works her way back until she finds a likely suspect.  "Would you mind standing up so a pregnant woman could be seated?" she asks.  "I've been up all night and I'm completely worn out.  My legs are aching and my rear is so sore!"  The gentleman stands and provides the seat for her.  Wanting to continue the conversation with the lovely creature he asked, "How far along are you, Dear?"  As she applied her lipstick in her mirror, she replied, "About seven minutes, Sweetie!  Thanks, awfully."
