James Hetfield & Dave Mustaine Laugh “Four Horsemen”

There’s an old saying — “laughter is the best medicine.” And one Metallica fan has taken that to a creepy level.

The YouTube user Lars Von Retriever has put together a bunch of clips of James Hetfield and ex-Metallica guitarist and Megadeth frontman Dave Mustaine laughing, and synched them up to an instrumental part of “The Four Horsemen” from Kill ‘Em All.
