They Might Be Giants - Tubthumping
Not only does it make complete sense that TMBG perform this song for AV Club’s Undercover, not only is it awesome to see TMBG pile in as many people as possible to sing with them (and awesome/funny to see Dan Telfer rock out in the background), but I guarantee this will make you happy.
Fantastic. Also, Flans was channeling Ira Glass there at the beginning, wasn’t he? Weird.
