Gross of Condoms

A man went into a drugstore on Friday afternoon and bought a gross of condoms. On Monday morning, he returned looking very upset and demanded to see the manager.

The clerk summoned the manager who asked the man "how can I help you, sir."

The man said, "I bought a gross of condoms here last Friday and I found that there were only 143 in the box."

The manager, with a pained expression on his face, replied, "I'm very sorry, sir. I hope it didn't spoil your weekend."
