Addiction is an ailment that plagues many rockstars. Some are addicted to drugs, some are alcoholics, some are hooked on women, and others are addicted to EVERYTHING. It really is a terrible thing. Dave Grohl's addiction is...coffee (and being awesome, but that's a different post). His problem is spiraling out of control and I think it's time we perform an intervention. Don't believe me? Just watch the video...(and yes, I realize it's old, but that doesn't make it any less entertaining.)
