Throwaway Lines that became Catch Phrases

Indeed raises eyebrow

Going back a few years: “'Tain’t funny, McGee.”

“It’s not the years, it’s the mileage.”

“He’s dead, Jim.”

“Beam me up, Scotty” (which I believe was never actually said in that form in ST:TOS)

They used this line in American Reunion which I saw this weekend. I think I was the only one laughing when I heard it.

“Beam me up Scotty”, is the name of the trope for phrases we THINK were in works, but weren’t.

“One does not simply walk into Mordor.”

I was about to post that about every third line from that movie has taken on a life of its own.

Play it again, Sam (yes, I know.)
I’m shocked — shocked …
We’ll always have Paris.
I’m a drunkard.
I stick my neck out for nobody.
This could be the beginning of a beautiful friendship.
etc.

My understanding is that “Different Strokes” the line “What cha talkin 'bout, Willis?” was written
as an ordinary piece of dialogue. But when Gary Coleman said it in a distinct style, it became a catchphrase.

There have been some musicians who have written lines that they were asked about far longer than they anticipated. "“Hope I Die before I get old” by Pete Townshend of The Who and “Too old to Rock n roll,and too young to die” by Ian Anderson of Jethro Tull
