Feeling a bit sluggish in the wake of a barbecue-stuffed, margarita-soaked, backyard fireworks-blasted 4th of July celebration? We’ll admit it — we’re right there with you. So we’re especially grateful to They Might Be Giants for coaxing a smile onto our faces this post-holiday Tuesday. As part of their excellent “A.V. Undercover” series, A.V. Club has posted a video of our favorite geek band covering Chumbawamba’s ridiculous ’90s drinking anthem “Tubthumping” — crammed in a tiny room with Onion staffers serving as backup singers. The surplus of nerdy energy in the room (not to mention John Flansburgh’s impressive falsetto) is sure to brighten your day. Watch it here.
