* EarWorm: HAMMA-MAN! HAMMA!
* FridgeLogic: In "Defeated Graffiti" Stanley needs quarters to call the police even though emergency numbers are free.
** Ok follow me on this: Gramps was the Hammerman. Ok, fine. He needs a NEW Hammerman because, somehow, he's gotten to old to use magic...alright no problem. The magic takes a toll on his body, after a while he couldn't contain it any more. Basically the plot to MCU Ant-Man. Hold on. So the theme says "Gramps and HIS GRANDDAUGHTER". Excuse me? He has a granddaughter, meaning he has a son or daughter already? Where are they? Why not give them the shoes? Let's assume it's daughter and he wanted to only pass it to a male, or was forced to even, she has a DAUGHTER! Where is she!? And if it IS a son, where is he? Why leave your kid with your dad and split? Did they die? Are they just deadbeats? Is that why the hypothetical son or daughter is unworthy of the power? We never know because they never even address this. Now, of course, the out-of-universe reason is the same reason why Donald and Scrooge are both 'uncles' and never have kids, or why Pop-Eye and Olive are 'babysitting', or why Jackie is the 'uncle' of Jade in Jackie Chan Adventures and so on--Western cartoons emphasize distant familial relations for some reason. But here it introduces a massive plot hole which is NEVER BROUGHT UP ONCE in the entire show! One which the show, not only draws attention to by putting it in the opening theme, but HINGES on since otherwise Stanley is irrelevant!
** The theme song.
** For the show itself, from the choppy animation to the cheesy raps and lines.
