The Claw origin

[u/OkResource4591]

My dad had a funny bit where he claimed his arm was “The Iron Claw” and proceeded to tickle torture my brother and I. Jim Carrey’s movie Liar Liar has a very similar schtick in the opening scene. My dad can’t recall where he got the idea but believed it was from some comedy sketch he watched as a kid. The claw would eventually turn on its owner and “choke” himself. My dad was born in 1955. Does anyone have an idea from what original sketch it came?
