"Let's sit in my car and sing Desperado" he said, and he handed her a bottle of mouth wash. "Is there going to be kissing?" she asked. "No. Here, rinse and spit" he said. Reconsidering, he said "Maybe later. But we really need to sing right this song right now". So they did, and they never kissed. The mouthwash was good, and the next day she bought the same brand. She still uses it now, every time she wants to sing.
