Clyde Crashcup is a fictional character from the early 1960s animated television series The Alvin Show. He is a scientist in a white coat who tends to "invent" things that had already been invented; his experiments invariably fail. He usually invented by penciling the concept in air, with the picture becoming the actual object. The character has also appeared in comics and other Alvin and the Chipmunks works after The Alvin Show.
