arisu, Schmendrick is one of my all-time favorites. I just blocked on his lines the last couple of times I posted to this thread. Of course, The Last Unicorn is full of good lines…so, naturally, here are a few more:
Butterfly: “It’s just you and me, moth…hand to hand to hand to hand to hand to hand…”
Mommy Fortuna: “The harpy’s as real as you are, and just as immortal. And she was just as easy to capture, if you want to know.”
Unicorn: “Do not boast, old woman. Your death sits in that cage…and she hears you.”
Schmendrick: “My dear, you deserve the services of a first-rate magician, but I’m afraid you’ll have to make do with a second-rate pickpocket.”
Schmendrick: “Oh my god, I’m engaged to a Douglas Fir!”
Molly: “Why must you always speak in riddles?”
Peg-legged, Eye-patched Cat: “Because I be what I be. I would tell you what you want to know if I could, mum, but I be a cat, and no cat anywhere ever gave anyone a straight answer, arrr.”
Lir: “She just looked at me, and I was sorry I had killed the thing…sorry for killing a dragon.”
Wizard: “Schmendrick, my boy, so good to see you!”
Haggard: “He is here to take your place. He is now my royal magician.”
Wizard: “Schmendrick? The ‘Runeless Wonder’?”
Brigand, yanking Schmendrick out of a tree: “Mind your heads, lads. It’s rainin’ ninnies.”
Lir: “Do something! You have the power! I will kill you if you don’t do something!”
Schmendrick: “I cannot! Not all the magic in the world can help her now.”
Molly: “Then what is magic for? What is the use of wizardry, if it cannot even save a unicorn?”
Schmendrick: “That’s what heroes are for.”
and, of course,
Schmendrick: “She will remember your heart when men are fairy tales in books written by rabbits. Of all unicorns, she is the only one who knows what regret is - and love.”

Another explosion as the building behind them smokes

From Babe:
“Christmas means carnage!!!”
“Where did you get this motorbike?”
“From Zed.”
“Who is Zed.”
“Zed’s dead, baby.”
“Of course he has a knife. We all have knives. It’s 1183 and we’re barbarians.”
“Sir, is it true that your real name is Nathan Huffheinz?” “Yeah, so, what of it?” “Well, sir, why did you change it?” “Would you buy furniture from a store called ‘Unpainted Huffheinz?’”
“The greatest trick the devil ever played was convincing the world he didn’t exist.”
“You are an errand boy, sent by grocery clerks to collect a bill.”
“Eat lead, you son of a bitch.”
“You wore blue, the Germans wore gray.”
“Its the stuff that dreams are made of.”
“I’m not really bad, I’m just drawn that way.”
“Sorry, son. But I thought you were one of them.”
“They come in through the door, Dad.”
“And YOU…don’t like me, anyway.”
“He reminds me a lot of Donna Reed, especially around the eyes.”
“I came here to kick ass and chew bubblegum…and I’m all out of bubblegum.” (Bonus points if you can name this movie!)

Another good line

I like that one, too! I use it every chance I get, too. 
Also the one in my sig from Ferris Bueller’s Day Off.
Has no one here seen The Crow?

Above from the Matrix
Not a movie, but from the Red Dwarf series V episode “The Inquisitor”…
(need to know: Lister and Kryten are about to be killed by the Inquisitor when another Kryten from the future pops into existence behind the Inquisitor and knocks him over, followed by a bit of hasty dialogue, then…)
Present Krtyen: “But what happens to you… me… us?”
Future Kryten: “I’m afraid we get killed.”
Present Kryten: “Killed?! How?”
Future Kryten: “While I’m standing here explaining this to you the Inquisitor jumps me from behind like this… argh!”
Seen it a million times but it always cracks me up. grins
Better though is (the original) Kryten’s line from his episode in serries II: “Swivel on it punk!”, but you need to have seen the whole episode to appreciate that one.
I’ve seen The Crow, and remember many lines from it. Unfortunately, most of them depress me, so I don’t use them. I prefer humorous or profound quotes to just plain grim ones. (Yes, I know there are non-grim quotes, like “It can’t rain all the time.”, but it’s the grim ones that spring to mind).
I have been known to call people “saprophyte mother!&@%*^$”, though. 
A couple from Harrison Ford:
“Whacking–I’m hell at whacking.”-Witness
