Dance of jokes

A stranger, led by his friend and a doctor, went to a dance held by a hospital for the deaf.

"How to invite deaf-mute girls to dance?"

"Just smile at her and nod your head." A friend told him.

"Dear, when will you dance with me? You haven't danced with me for an hour! "

"I know, dear, but I don't know how to get rid of this deaf and dumb guy!
