John Linnell from They Might Be Giants did an "impression" of David Byrne from Talking Heads. We're all very intrigued at how John managed to decide that this is what David sounds like!
I don't know the origin/context of this clip unfortunately, I've just seen it on Tumblr and it wasn't on YouTube yet so I decided it should be here too.

I find this funnier when considering the context that the two have worked together - John Linnell plays accordion on the 2004 David Byrne track Civilization, from his album Grown Backwards (I would recommend it, it's a very cool track)
