Fake Moustache Puns

It was a blessing in disguise

A piece of string goes to the local bar for a drink. The bartender says, "We don't serve string here" and kicks him out. He puts on a cowboy hat and a fake moustache and tries again. The bartender sees through his disguise and kicks him out again. Dejected, he sits on the sidewalk until he gets a great idea. He ties himself into a knot and combs out one of his ends. After he enters the bar the bartender says, "Hey! Aren't you the piece of string I just kicked out, twice?" and the piece of string says, "No, I'm a frayed knot."
