The metal pipe clang became a staple meme effect online because its exaggerated crash works for almost any fall or collision, even when no pipe is on screen.

The contrast between a serious industrial crash and a silly vocal reaction is what keeps it in rotation, letting a tiny mistake sound painfully huge.
