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