Last week on Mad Men, Ken Cosgrove did a nifty jig, so right on cue, here is your “Ken Cosgrove Dancing to Daft Punk” mash-up.

Wouldn’t anything besides the Panda Bear song have made more sense? — but as the old saying goes, don’t look a gift Daft Punk viral video in the mouth. Our mother taught us that.
