Lisa: Isn't mid-season just a dumping ground for second-rate shows that weren't good enough for the fall schedule?
Homer: You're thinking of all the other years. This year's shows are classic. There's "The Laughter Family" — that's animated. Networks like animation 'cause they don't have to pay the actors squat!
Ned Flanders: (appears with voice provided by Karl Wiedergott) Plus, they can replace them and no one can tell the diddley-ifference!
— The Simpsons, "Homer to the Max"
Corny Collins: You can't fire Corny Collins from the Corny Collins Show!
Velma Von Tussle: They do it all the time on Lassie!
"Duffman can never die! Only the actors who play him!"
— Duffman, The Simpsons, "Jaws Wired Shut"
"Wait a second, you're not Kirstie Alley! Who are you?!"
Dr. Manhattan: You know what's interesting?
Dr. Manhattan: I can understand anything about nuclear and particle physics.
Dr. Manhattan: And I can invent technological advances decades ahead of their time.
Dr. Manhattan: And I can even understand the concept of time to the point where I do not experience it linearly.
Dr. Manhattan: And even I don't know how Liev Schrieber could become Tyler Mane.
Ironman: In my next movie Rhodey will become War Machine.
Kimimaro: Didn't you used to be British?
Kabuto: Didn't you used to be healthy?
"You're looking at a woman who lived through two world wars, fifteen vendettas, four major operations, and two Darrins on Bewitched!"

"Rommie, the ship itself, was a sentient, thinking, feeling Artificial Intelligence...in Season 5, the whole show took a weird turn, with the crew separated and stuck on several identical desert planets. Most problematically, they didn't actually have a spaceship any more. Neither, for that matter, did they have Rommie. The actress took some time off to have a kid and to star in Jason X, neither of which seem like terribly conscientious career choices.
So the ship's genius, Shamus Zelazney Harper, who first designed the android Rommie rebuilds her as Doyle, a blonder, sluttier version of Rommie with just enough memories to provide continuity. No other explanation: she broke, we done fixed her up as best we could boss.
They eventually 'rebuilt' Rommie as herself when Lexa Doig returned after her pregnancy; when asked how her new body felt (one that had put on a bit after nine months of conceiving and then delivering a human child) Rommie responds, 'sturdy.'"
Chris: Two things I want to mention here. First, as we’ve said before, this is Jor-El, who looks just like Clark. Which would be fine, except that we know that by the time Krypton blows up, Jor-El looks like Julian Sands, a.k.a. Warlock. And then, after he dies (?!) he’s Terence Stamp. So apparently the aging process on Krypton makes you look like a completely different person every ten years.
David: I don’t know how to break this to you, but Clark’s actually a Time Lord.
Chris: That would explain an awful lot. Especially how he keeps swapping out hot female companions every few years too.
