The King William

A man walks into a pub and orders a drink. After his first sip, he hears a high-pitched voice.

"Hey mister! Nice coat!" it says.

He looks around, doesn't see anything, and shrugs it off. After a little bit, he takes another sip and hears the voice again.

"Hey mister! Great shoes!"

Again, he looks around, sees nothing but the bartender who is busy attending to other customers. Shaking his head, he sips once more.

"Hey mister! Cool shirt!"

He puts down his drink, puzzled by this phantom voice, and signals to the bartender, who comes over.

"Hey," he begins, "what is that high-pitched voice I keep hearing?"

"Oh, those are the peanuts," the barman replies.
"They're complimentary."
