First off, he's blue. Secondly, his logo includes hearts. I just don't see Brooksie wearing anything with hearts on it. An 'I Heart Mom' tattoo, maybe. Finally, he's in terrible hockey shape. I know you need that belly for Care Bear Staring, but someone needs to lay off the Butterfingers. Nope, doesn't fit.
Lastly we have Mr. Grumpy, created by the great Roger Hargreaves.
Once again, we have the blueish complexion as a distinct difference. Both do have the solid, square jaw and are built like bricks. I just don't think Brooks would really wear a green top hat.
Nope, I frankly don't think the 'Grumpy' nickname will stick this season. That is, unless Mr. Laughlin starts throwing it out there on a regular basis.
