An old Jewish man gets married to a lively young girl but it turns out that he can't get the girl to reach an orgasm. When all the free advice from his friends fails to produce the goods he resolves to go to his doctor.
The doctor tells him to go to a specialist psychiatrist. Both the old man and his young bride attend sessions at the psychiatrists for some time.
The result is that the psychiatrist says the cure is to get a fit young stud to stand beside them wafting a towel over them while they make love.
They go away and try this a dozen times or more with absolutely no success at all.
The young bride suggests they swap places and invites the young buck to do the shagging and the husband to waive the towel.This works brilliantly and the girl is thrashing around and screaming like a banshee.
The old guy is flapping like mad and shouts, “Yes you young schmuck this is how to wave a towel.”
