Francis X. Clampazzo, better known as Clamps, is one of the recurring antagonists in Futurama. He is a robot who is a part of Robot Mafia and works for Donbot.
Clamps is a bronze robot. He has a row of rivets on the right side of his face. Clamps' personality is sarcastic, and highly aggressive, reflecting that of Joe Pesci's character Tommy DeVito, as well as his high pitch voice.
Clamps love to use his own clamps at "every opportunity" but his clamps are often unnecessary in any given situation. He is antagonized by Joey Mousepad when Joey suggests to use them. In The Silence Of The Clamps, he works in Planet Express after Bender is in the witness protection program. The crew starts to trust him except Zoidberg. Francis goes into the moon to find Bender, who is actually Billy West.
Francis tries to kill Billy, but Zoidberg prevents him from doing so and they fight. Francis tries to kill Zoidberg by crushing his skull but Zoidberg gains the upper hand and defeats Francis by cutting off his clamps.
