Quotes: Took a Level in Dumbass

I think Homer gets stupider every year.
Professor Lawrence Pierce, The Simpsons, "The Simpsons' 138th Episode Spectacular"

'Greyhound Three — we're stuck in the mud!' Oh, the irony of that statement. One criticism about the UNIT stories midway through the Pertwee era is that the whole organisation is supposedly starting to feel a little bit too cosy and indolent. Having Mike turn up at the start of the story and state that he hopes something dreadful happens soon because he is bored isn't exactly the most dynamic of introductions. It suggests that they just hang around between invasions and drink army cocoa and Benton's brew. Once upon a time this organisation could pull off impressive resources to take down any alien menace, and now it is reduced to a bouffant-bothered Brigadier huffing because nobody will escort him to prom—sorry, to the demonstration of TOM-TIT. (It's a choice between Yates and Benton, and one is duty officer and the other is heading home to knit a tea cosy). The Brig has been lobotomised to such an extent that he needs jolly Sergeant Benton to explain the science to him; how the mighty have fallen. It's not as if the TOM-TIT technobabble is especially hard to grasp, even if you are a pompous military idiot. I think if you rosy up the Brig's cheeks, put a wind up key on his back and have him marching around banging drums in the background of scenes he would look less of a goon than he does when getting involved with the action.

This is amazing. Are all the babyfaces on this show completely stupid? I'm not even talking kind of naive, or dopey, or just even low-IQ; I mean "dangerously-unable-to-function-on-his-own" stupid. Like, "If you gave this guy a cup of applesauce and a spoon, he would probably drown"-stupid. Because that's what Mick Foley and Jeff Jarrett are like on this show.

Chris: Donatello says the dumbest thing I have ever heard: 'If we die in the past, does that mean we don’t get born in the future?' F**k off, Donatello.
Matt: This is the same Donatello who figured out the physics of time travel earlier. The intelligence level of the turtles is Homer Simpson-like in how much it varies depending on the plot or a joke.
Chris: April doesn’t realize she’s in the past even when a bunch of Samurai are walking around referring to her as a witch and trying to chop up a Walkman...Everyone in this movie is an idiot.
—Chris Sims and Matt Wilson on Teenage Mutant Ninja Turtles III

The only character able to fool Indiana Jones should be a sexy blonde woman or a sexy Indian child! I know Mac and Indiana had a history fighting in WWII, or whatever; but after awhile the double and triple-crosses started to make Indiana Jones look like a stupid retard. If Mac was "C.I.A.", then why didn't he help him escape the first time, when they had a chance to stop the Russians from the start? Indiana would not tolerate such foolishness and would not be so stupid! Younger Indy probably woulda just shot Mac!
