A man goes to a bar. He goes to the dance floor with three ladies.
He says to them if I can guess the color of your underwear you have to dance with me.
His shoe is shiny so he stuck his foot under the 2 of 3 girls and guessed the color of underwears correctly.
When he stuck his foot under the third girl he asked her if she was wearing any underwear.
She replied "No."
He said "Good because I thought I had a crack in my shoe."
