String a few funnies together

[VIP2006]

A piece of string walks into a bar and orders a beer.

The barman says "Sorry, we don't serve string in here."

So the piece of string goes outside and decides to change his appearance by tying himself in a half-hitch and ruffling up his ends.

Suitably disguised, the piece of string goes back into the bar and orders a beer.

The barman says "Say, aren't you a piece of string?"

The string says "No, I'm a frayed knot!"
