The first time I went to a drug store to buy condoms, I was waited on by a 
beautiful young woman. She asked what size I wanted and I said I wasn't 
sure. So she asked now big I was and I said, "Compared to what?" She held 
up one finger and asked if I was that big. I said, "I'm bigger than that." 
Then she held up two fingers and asked if I was that big. I said, "I'm 
bigger than that." Then she held up three fingers and asked if I was that 
big. I said, "I'm about that big." She put the three fingers in her mouth 
and said, "You're a medium."
