On Monday night, Foo Fighters played a surprise show at Washington D.C.’s 9:30 Club. In the fan-shot footage below, you can see frontman Dave Grohl climb on top of a bar during the band’s performance of “Monkey Wrench.” The Nirvana drummer then proceeds to slam a shot (Jägermeister, according to Consequence Of Sound) and remains on top of the bar shredding for another two minutes. Watch the footage below, and let us know what you think. (Most of the action happens a little after the one-minute mark.)

If you missed it, watch Grohl remember his first time hearing Soundgarden's Superunknown.
