Having lunch one day, a sex therapist said to her friend,
"According to a survey we just completed, ninety percent of all
people masturbate in the shower. The other ten percent of them

"Really?" asked the friend.

The therapist shook her head and proceeded to ask, "And do you
know what song they sing?"

The friend shook her head and replied, "No."

The therapist replied, "I didn't think so."
