Much has been said throughout history about “too much of a good thing,” and for Them Crooked Vultures drummer Dave Grohl, the “good thing” of choice is coffee.

Whether coffee is good or bad for you is something best left to doctors and nutritionists to debate, but Grohl’s reported five-pot-a-day intake pushed his body a bit past its ability to deal with that much caffeine. Who the heck wouldn’t be bouncing off the walls, or perhaps ceilings with that much caffeine in them?

Being the fun-loving and crazy guys that rock stars tend to be, the guys from the Vultures put together a little video recently that featured a caffeine-crazed Grohl screaming for “fresh pots,” hammering away at lightning speed on his drum kit, and playing some kind of 4-stringed instrument that looks like it may be some variation of the mandolin or something.

The video is amusing, and probably the kind of thing you would expect from crazy rock musician types. Hey, who doesn’t like to have a little fun once in a while and act a bit silly in the process?

Apparently things went from silly to decidedly more serious when Grohl had to be rushed to the doctor after suffering from the effects of too much caffeine. The incident unfolded just two weeks after the video was shot.

According to a few quick tidbits dredged up on the web, too much caffeine can lead to symptoms such as nervousness, gastrointestinal disturbance (ouch!), muscle twitching, rambling flow of thought and speech, and rapid heartbeat.

It is also said that caffeine overdoes can be fatal in some cases, but Grohl was probably nowhere near the level it would take to actually kill him. Let’s hope so, anyway!

The video entitled “Fresh Pots!” can be enjoyed below, and we’re glad to hear that Grohl came through his ordeal just fine and has reduced his intake of coffee as a result.
