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 !!"
