Thank you people for making me feel better about some of the episodes I don't like!
Out Of Commission is BY FAR the worst episode in the series history. I've had people try to explain to me how good it is, but the person who voiced the cart should never be allowed to speak again. Brutal voice and a boring, annoying episode.
Quips is the next one that comes to mind. Again, that voice should be retired to the halls of shame. A few lame jokes? OK. 100? Holy crap, never again.
Those are pretty much the only two episodes that I will literally turn off if they come on my tv. Outside of those, most of my least favorites are from this season when I thought the show was losing steam (and for a while, I thought was done for good until this recent string of greatness). Firework Run, Sandwich of Death, Ace Balthazar Lives, Caveman, and That's My Television were all a part of a multi-month set that I hated. Mostly for the very repetitive nature/theme of all the episodes. Also didn't care much for Carter and Briggs, as again, I had been overloaded by the 80's theme.
Aside from that, everything else was at least OK. Thought episodes like The Best VHS in the World, Skunked, and the infamous Unicorns episode were all pretty mediocre. But nearly everything from the first three season are genuinely awesome.
As for some of the discussions in here - I love Rap It Up! Something about that episode is brilliant, and it honestly might be one of my favorites of all time. I enjoyed the music and the visuals during the rap battle were great. And I liked the Best Burger episode. Yeah, Benson eating it at the end was a huge **** move but the rest of the episode was pretty hilarious, and I liked the classic music slow motion thing.
