Watch the Ghostbusters take on the Mythbusters in an epic rap battle

By Robert McNamara

It's common sense that any dispute can be settled by a simple rap-off and the latest in the 'Epic Rap Battles of History' Youtube series is the best yet.

It pits '80s icons the Ghostbusters against American TV sensations the Mythbusters.

If that wasn't enough to whet the appetite in the nerd in all of us, there's also a dancing Marshmallow man dropping some wicked rhymes.

Who you gonna call?
