When an Irishman couldn't get a dance his friend decided to tell him the truth.
"Look," his friend said, "it's the smell from your socks. Go home and change them and you will have no more trouble!"
Later in the evening the Irishman complained that he still couldn't get a dance.
"Did you change your socks?" his friend asked.
"Of course I did," replied the Irishman pulling them from his pocket.
