In a crowded Nashville bar, I was sitting on a stool - back to the bar - listening to a jazz band on a stage across the room. A girl backed up, between my legs to let someone pass in front of her. When she realized what she had backed onto she turned her head and said, "I'm sorry." I leaned forward and said into her ear, "I'm not!" She stayed there, moving slowly with the music, until the band's set was over.
Only after the girl walked away without another word, leaving me with a boner, did I think to look at my date on the next stool. My date asked me if I knew the girl. When I said, "No" my date date said, "That was hot, let's go!" It was a good night.
