Little Jimmy just finding out about sex decided he need to get some rubbers. So he goes to the drug store.

Upon entering the store the pharmacist is out to lunch, but 80 year old Mable is behind the counter.

Can I help you little boy she says? He stutters for a few seconds and then asks for rubbers. She says yes sir what size? Size, I don't know. Well go out the front door and around back there's a fence with holes. Above the holes there are numbers. Try each one until you find the one that fits best. Then come back in and tell me what number.

With this he walks outside. Not having sex in a really long time Mable runs out the back door. She matchs Jimmy hole for hole. she ride the hell out his little tool.

After about an hour Jimmy has finally tried every hole. Tired out Jimmy walks back into the store.

Mable rushes back into the store with a big smile. Well Jimmy did you find your size? With this Jimmy says F**K the rubbers, sell me that FENCE.......
