We are HUGE movie quoters... I swear every conversation ends up with a movie quote in it somewhere. Princess Bride quotes get used all the time... that is, IMHO, one of the most quotable movies of all time..
"Have fun storming the castle!" (when anyone is leaving to go do anything)
"Life is not fair, Highness. Anyone who says otherwise is selling something." (when one of the children says "Its not fair!" about something)
"Hello. My name is Inigo Montoya. You killed my father. Prepare to die." (just because it's fun...

)
"Rodents of Unusual Size? I don't think they exist." (Again, just fun)
"Never go in against a Sicilian when death is on the line!" (When my husband challenges me to do something)
"If you're in such a hurry, you could lower a rope or a tree branch or find something useful to do." (When someone is rushing me)
"INCONCEIVABLE!" (self-explanatory LOL)
"You keep using that word. I do not think it means what you think it means." (when one of the children is over-using a word)
"I've worked hard to become so." (when someone complements you - or insults you - on being good at - or evil about - something)
"He's been mostly dead all day." (when someone isn't well or has had a bad day)
"Don't even think about trying to escape" (always said after someone coughs that dry wretching choking cough done in that scene in the movie right before that line)
"EVERYBODY MOVE!" (always done quietly but in Andre the Giant's voice in very crowded places... i.e. Disney World)
And a host of others.. we know Princess Bride by heart LOL.
************************
Quotes we do that are NOT from Princess Bride....
"Don't be ReeDIKulus!!" (in Balki Bartomous' voice from the old Tv show Perfect Strangers)
"And now we are so happy, we do The Dance of Joy!" (Also Balki - always said when things turn out wonderfully)
"And me, with no ointment." (Balki again - always said in a woeful tone of voice, always the response whenever anyone announces "I have a plan!") - I will explain if anyone needs an explanation...
"I shouldn't have come. I'm endangering the mission." (when things are NOT going well - Luke Skywalker, in Return of the Jedi)
"These are not the droids you are looking for... move along, move along" (when we want the children to mind their own business - Star Wars)
"SHH! Even before you start, that was a pre-emptive "shh!" Just know that I have a whole bag of "shh!" with your name on it." (from Austin Powers - said to the children when they need to SHHH! of course)
"The Defense Department regrets to inform you that your sons are dead because they were stupid." (said by me whenever my husband or his friends are being idiots - Top Gun)
"I hate it when it does that..." (from the Top Gun "giving him the bird" scene - acompanies the appropriate action...)
If that is a ____, or If he is a ____, etc then "I am the King of Cashmere" (a twisting of a line from "Willow" to suit whatever situation I am in)
And finally, lines from another of my most quotable movies of all time "Real Genius". They don't have to fit any situation, I just throw them into conversations.
"It's a Moral Imperative!" (anytime we MUST do something)
"Why is that toy on your head? Because if I wear it any place else, it chafes."
"Kent puts his name on his license plate. My mom does the same thing to my underwear. Your mom puts license plates in your underwear? How do you sit?"
"Was it a dream where you see yourself standing in sort of sun-god robes on a pyramid with a thousand naked women screaming and throwing little pickles at you? No... Why am I the only one who has that dream?"
"Would you qualify that as a launch problem or a design problem?" (always asked whenever anything doesn't work out as I had planned)
Love movie quotes!
ETA! POTC quotes! Forgot all about those!
"Disinclined to aquiesce..." when I am saying no to someone.
"Why is the rum gone?"
"Its Elizabeth.. hide the rum!"
"Don't think I deserved that.."
"I've got a jar of dirt..."
"Where's the thump-thump?"
"You need to find yourself a girl, mate."
"Parlay!" and "That would be the French, actually..."
and many more....
