Description:  Clyde Crashcup is a kooky, inept scientist character from the 1960s cartoon The Alvin Show who constantly "invents" things that already exist. He is a tall, thin man with a mustache and is always wearing a lab coat. His silent, pudgy sidekick, Leonardo, often tries to warn him of impending failure, but Clyde is oblivious to his assistant's advice.

Character: A well-meaning but clueless inventor who works on a variety of projects.

Sidekick: A silent assistant named Leonardo, who has a knack for predicting disaster and tries to warn Clyde through gestures or by whispering in his ear.

Inventions: Clyde's "inventions" are often things that already exist, like a bathtub, which he creates with a fatal flaw like forgetting the drain. His experiments usually fail in a comedic way.

Appearance: He is depicted as a tall, slim man with pale skin, a long nose, and a dark nose-stache and hair.

Origin: He is a recurring character in The Alvin Show and has also appeared in comics and other Alvin and the Chipmunks works.
