Challenge us with a non-famous line from a movie

“Wow! This place sure is crawlin’ with celebrities. I’m the only person here I never heard of.”

9 to 5??

Beetlejuice

Bingo

“You’re not on the drugs, are ya?”

It’s spoken by Sam Elliott.

I tried to Google it to satisfy my own curiosity, and couldn’t find anything.

“Let me tell you about this guy I knew; Jack. Mean kid. Bad seed. Hurt people.”
“I like him already!”

Batman (the Michael Keaton version)

Correct.

Is this the Wolverine Origins movie? The old farmer who takes in Logan on the run after his adamantium injection?

Yep.

“Haven’t you heard of science’s newest triumph, the doorbell?”

Monsters vs. Aliens?

I’m going to throw in a quote from a short (don’t worry, I’m sure you’ve seen it):

“Isn’t m-m-modern science wonderful? We used to have to use s-s-stairs!”

You got it!

“You’re lucky I can’t breathe, or I’d walk all up and down your ass.”

“Could be raining.”

Young Frankenstein

Whenever we watch The Two Towers, I quote this line when Theoden and co. see 10,000 orcs bearing down on them, just before they realize they’re probably screwed - and then on top of it, it starts to pour.
