A young man bought a new pair of boots of which he was very proud. He decided to go dancing and give them a try.
After dancing with one lady for a few minutes, he said, "I bet you I can guess the color of your panties."
"OK," she replied. "What color do you think they are?"
"Blue," he replied.
"How did you know that?" she asked.
"I saw the reflection in my shiny new boots," he said.
"Here, she said, "dance with my sister and tell me what color she has on."
After dancing a while, the young man started rubbing his toes on his pant cuffs and started to dance again.
After a few minutes, he ask the new lady, "What color panties do you have on? I can't seem to make them out."
To which she replied, "I don't have any panties on."
With a sigh of relief, the young man said, "Oh good! For a minute I thought I had a crack in my new boots."
