Stupid pun

A fellow came into a restaurant, sat down at the bar, and ordered a drink. As he sat there sipping his drink, he heard this tiny voice that said "Nice haircut!". The man looked around but didn't see anyone. A few minutes passed and once again this same small voice said "What a nice tie you have on!" He turned completely around, looking carefully, but there was nobody there. Getting a little uneasy, he heard the voice again. "That sure is a nice jacket your wearing!".

Wondering what was going on, he called the bartender over and asked, "Bartender, Am I going crazy? I keep hearing this tiny voice and yet there's nobody around." The bartender replied, "Oh that's just the peanuts. They're complimentary."
