It is a bit tricky to review a show as ADD as \'Robot Chicken\' at length. However, the short version for this episode is that \'Winter Pet Games\' and the Muppet Show Band \'Behind the Music\' bit just absolutely cracked me up.
\'Winter Pet Games\' is just one of those wonderfully horrible sketches that either makes you to fall over laughing, or say \"Really? This is F\'n stupid.\" It is the sort of comedy that constitutes the heart of this show and which makes this show a f'n force.
The Muppet Band \'Behind the Music\' thing is the sort of dated reference that most viewers of this show are probably borderline old enough to appreciate. But, like all well-presented obscure reference comedic bits, this one can be enjoyed by extrapolating the facts in the context of the sketch. It is a delight even if you only kindasorta remember there was a muppet band. A fine episode to be sure.
