Erections
 

This poor guy went to hospital for a circumcision, but because
of a mix up, he ended up having a complete sex change.

All the doctors and nurses had gathered around his bed as he
was waking up so they could give him the bad news.

Naturally, the poor guy went to pieces and started crying when
they explained what had happened to him.

"Damn!" he moaned, "this means I'll never be able to experience
an erection ever again!"

"Of course you will," one of the doctors soothed. "It'll just
have to be someone else's."
