They Might be Giants - Birdhouse in Your Soul

One of my favorite songs of the last twenty years. Hat tip to Atrios for linking to this vid and reminding me of it.

The nerdy quality of TMBG that gets the most notice is the quirkiness. Less noticed is another nerdy quality, that of being deeply knowledgeable about some topic. In this case, songwriting. These guys know what they're doing.
