OK, right up front let’s be clear — this is not a real ad. However, the message it sends — sharks are attracted to blood — is well demonstrated. The “ad” appears in the very rotten film Movie 43 and is for Tampax. It urges woman to make sure their tampons don’t leatkso, ya know, they don’t get sniffed out by a giant shark that will tear you a part with spooftastic, Jaws-style hilarity.
