Heard This On My Last Flight With Southwest From The Captain:

It was an early flight, 3am to be exact. There were only a handful of passengers. A rather introverted man sat in the very back away from everyone else on board. While sitting there, early in the flight, the man heard someone whisper, "you are quite the handsome fellow".

The man was puzzled and was looking all around to find who said it. No one was near him. A few minutes later, he heard the same voice whisper again, " you are so well dressed". Again the man looked around; no one there. He was beginning to feel uncomfortable.

Once more, the voice returned. " do you work out, because you look like you work out."

The man, at this point a little freaked out, waived down an attendant who had started beverage orders up front. The attendant came to the man and the man told him what was going on.

When he asked "So where the hell is this voice coming from?!" The flight attendant smiled and said "Oh! Those are our complimentary peanuts!".
