When Ted Nelson is dead on the stairs, Tom says that its ironic cos he didn't like stairs. I don't remember hearing that in the movie or anything.... and it didn't sound like Tom had just plucked it out of thin air.
Great ep, especially that bit on the strange moving trolley thing (how far is your locker?) and the diabolical acting of Burr DeBenning.
'No Steve, no. Don't Steve.'
And what was that thing Blake found by the alien parents car? Was it a piece of a guard dog, or a person, or the Melting Man?

One of my all-time favorite MST3k scenes is with the repulsive alien old mom and her equally alien old boyfriend:

"My mom ate candy and I turned out fine!"

Alien Boyfriend: "Oh, my ticker's really going!"
CROW: *AB* "And my heart, too!"

"Now I'll squeeze those lemons and let the juice run down my body!"

AB: "Hellleennn..."
Alien Mom: "Harrollldd..."
Crow: "What is happening!?"

"Let's hide in one of your skin flaps!"

AM: "Now get busy."
Mike: *AB* "No, that's later, dear."

"The Getaway!"

(When the title comes up)
“The George Hamilton story.”

Astronaut: “You’ve never seen anything until you’ve seen the Sun through the rings of Saturn.”
(Footage of solar flares)
Crow: “That’s not what this is, but we’ll show you a film that sort of suggests it.”

“Bedpan! Bed ... oh, never mind.”

“Hey, you got protoplasm in my peanut butter!”

“NASA’s a sucker for any Very Large Array salesman.”

(During the riveting “no crackers” scene)
“They made a mistake and just went home with the actors.”

(The severed head falls over a waterfall and lands on a ledge)
“On the bright side, at least I didn’t break my back.”

Ted: “Oh, God, it’s his ear.”
Mike (as Ted): “I’ve been following Van Gogh!”

Ted: “I thought I had him, but I lost him.”
Crow (as Ted): “And we’re out of crackers.”

Sheriff: “Hiya, Doc.”
Ted: “Neil.”
Crow (as Sheriff): “Well, I’d rather stand if you don’t mind.”

“I’ve been a sheriff most of this movie and I’ve never seen anything like it.”

(During a shot of Steve)
“I think his shampoo had the wrong pH.”

“And they were never seen again (cross your fingers).”

(Steve in the graveyard)
“God bless Drippy, and Runny, and Sticky ...”

“Oh, man, I’ve got this flashback memorised.”
“It’s like when you can’t get a song out of your head.”
“Hey, hum ‘Seasons in the Sun’ – that should dislodge it.”

(Another shot of Steve)
“Won that little scanning contest, but it cost me.”

“This is basically the same story as Frosty the Snowman.”

“Careful – the panelling is out-acting you.”

General: “Just call me Mike.”
Mike (as General): “Even though my name is Trent.”

“There’s a face you have to get used to.”

“Well, I suppose I could reminisce about my countdown again – that would kill some time.”

“Couldn’t they just put ‘ibid’ up on the screen, please?”

“This scene has been over several times, and they just won’t admit it!”

“This all sounds like music that was rejected by Wonderwoman.”

“The gooeyness of the long distance runner.”

“You know, immolation is the sincerest form of flattery.”

“Cape Kennedy was renamed Cape Ted Nelson ... and quickly renamed Cape Kennedy again.”

The Melting Man saves his friend from falling, only for said friend to be gunned down by a couple of red shirts seconds later.

What was the point?
