A Piece of string walked into a bar one day and asked for a pint.
The barman replied “I’m sorry but we don’t serve pieces of string in this establishment”
The Piece of string walked out of bar and round the corner where he jumped into the wall a few times, rolled about and tied himself up.
The Piece of string then walked back into the bar and asked for a pint again.
The barman gave him a hard look and replied “I’m sorry but aren’t you that piece of string I just refused to serve”
The Piece of string said “No, I’m a frayed knot”
