Canine Tying Puns

Hi. My name is DAK. A piece of string walks into a bar. The bartender says “sorry sir we don’t serve string here”. He then proceeds to tie him into a knot and throw in outside. Whilst outside, a pack of feral canines attack the piece of string until his fibers are loosened in a disheveled manner. The piece of string them proceeds to re enter the bar in need of medical assistance. “Hey, aren’t you the string I just threw out?” Asks the bartender. “No sir,” replies the string, “I’m a frayed knot”
