There's something about the show which I choose to take as a wink and a nod. Like the episode was a parody of itself or something. It felt like the resolution should have been that it was all a dream or so far in the future that UG's mind was screwed up or something. Maybe there was a couple not quite empty vodka bottles in his trash or something. He seemed not only dumber than usual, but drunk. The jokes really felt like they're making fun of the show itself. The "I'm a lightbulb" bit especially. Wouldn't it usually say "Good Morning."
Also noticed they're drawing him more like the wild style they use for the title cards. Especially his "WHAAAAAAAAAAAAT?!?!" reaction.
I'm hoping this is a one time thing, and they go back to more deviously written goofiness for the next episode. Not that this was bad, just strange. The previous episode was brilliant. Something like that, where they use UG's reality warping as a plot device.
Speaking of last episode... is it just me, or was Kevin doing his Shredder voice with a slightly exaggerated Japanese Accent when UG had that imagine spot, realizing that he was the enemy in disguise. Probably unintentional, but I kinda dug that.
