Puttin' on the Ritz was written by Irving Berlin in 1929 and became a standard about dressing up in style. Mel Brooks reused it for Young Frankenstein in 1974, staging it as a theatrical act where Frederick Frankenstein presents his creation to a scientific audience. The routine starts polished, then falls apart when the Monster is startled and loses control. Clips of his singing have circulated for years in edits and reaction videos, kept alive by how recognizable the melody and that strained delivery remain.
