Laughing Customer

[excelsior-1]

A man walks into a pharmacy, buys one condom, then walks out of the
store laughing hysterically. The pharmacist thinks this is weird,
but, hey, there's no law preventing weird people from buying
condoms. Maybe it's a good thing.

The next day, the man comes back to the store, purchases another
condom, and once again he leaves the store laughing wildly. This
piques the interest of the pharmacist. What's so funny about
buying a rubber, anyway? So he tells his clerk "If this guy ever
comes back, I want you to follow him to see where he goes."

Sure enough, the next day the laughing customer is back. He buys
the condom, starts cracking up, then leaves.

The pharmacist tells his clerk to go follow the guy.

About an hour later, the clerk comes back to the store.

"Did you follow him? Where did he go?" asks the pharmacist.

The clerk replies, "Your house."
