A horny young man went to a brothel..The lady at the counter asked him what his choice would be.

The man wanted to know what was available..

Lady - "On the first floor, we have the ex-models.. they are all slinky and sexy.. On the second floor, we have our ex-actresses...

they are all buxom and beautiful... On the third floor, we have our ex-teachers....they...

" Man - "Say no more! Lead me to the third floor !" Lady- "Are you sure...

I'm surprised that you would prefer ex-teachers to ex-models and ex-actresses..." Man- "It's obvious, ma'am...

teachers always make you do a thing over and over again...

until you're perfect at it !!"
