There are a lot of places to start with this clip from last night's episode of Greatest American Dog: for example, though the on-screen chyron gives the dog's name as "Galaxy," we're pretty sure that owner JD variously calls for "Gutsy," "Curtsy," and "Koyaanisqatsi." More entertaining, though, than JD's strange names or his hip-hop/breakdancing routine with a nonplussed Galaxy are the reaction shots from the judges, which run the gamut from open-mouthed incredulity to a suspenseful, physical performance of, "Should I applaud? Yes? Both hands? No, just the one. How will I clap, then? Why, I'll just hit the table in a few sharp strokes like I'm a bad nanny." [CBS]
