A man walks into a chemist, buys a condom, then walks out laughing hysterically. The pharmacist thinks this is weird, there's no law preventing weird people from buying condoms. Who knows, maybe it's a good thing.
The next day, the same man comes back to the store, purchases yet another condom, and once again he leaves in hysterics , the pharmacist thinks "What's could be so funny about buying a condom, anyway?" So he tells his assistant "If he ever comes back, I want you to follow him to see where he goes."
Sure enough, the next day the same man is back, he buys the condom, and again starts cracking up with laughter, then leaves. The pharmacist tells his assistant, to follow him.
About an hour later, the assistant comes back to the store. "Did you follow him? Where did he go?" asks the pharmacist.
The assistant replies "Your house."....
