Loop Head Puns

They see a sign at the door that says “No strings allowed.”

The first string tries to enter. “No strings allowed!” the bartender says.

The second string marches up angrily. “No strings allowed!” the bartender says.

Now the third string is mad. He pulls at his end & loops himself around several times, heading straight for the bartender.

The bartender squints, eyeing the string closely. “Are you a string?” he asks.

The string replies, “Nope, I’m a frayed knot.”
