Rumors of Infidelity

A co-worker informed George that George’s wife was being unfaithful everyday at 1:30 in the afternoon with George’s best friend.
Worried and hurt, George ran home at 1:30 to see if this was true. He came back to the office contented and relieved.
His co-worker meandered over and asked him how it went.
“Look,” said George. “Don’t start such terrible rumors! That guy isn’t my best friend. In fact I don’t even know him!”
