A string went into the bar and ordered a drink.

The bartender said "we
don't serve strings in here".

The string left and then returned a while later.

It stayed by the door
until a customer approached.

He told the man he would buy him a drink if
he would tie him in a knot and scruff him up.

The man agreed and the
string went up to the bar.

The bartender said," weren't you the string
that I told to leave?"

The string replied, "nope, frayed knot."
