I love The Springfield Files episode, so many classic quotes;
Moe: "Ah, jeez, it's the fed's - come on, lets get him back to Seaworld"
AlienBurns: "I bring you Love"
Dr. Hibbert: "Is that the kind of love between a man and a women? Or the love of a man for a cuban cigar?"
Lenny: "It's bringing love! Don't let it get away!"
Carl: "Break it's legs!"
Lisa: "You want an alien? This is your alien!" *shines flashlight*
AlienBurns: "Hello children, I bring you love."
Willy: "Argh, it's a monster! Kill it! KILL IT!"
Smithers: "It's not a monster, it's Mr Burns!"
Willy: "Awww, it's Mr Burns...KILL IT! KILL IT!"
Squeaky Voiced Teen: "And so concludes our tale. I'm Leonard Nimoy. Good night, and keep watching the skis. Uh, skies."
Dr Nick: "Don't worry, this won't hurt a bit - until I jam this down your throat!"
Dr Nick: "The best part was when he gave me his money"
Mulder: "Mr Simpson, we want you to recreate your every move the night you saw the alien."
Homer: "The evening began at the gentlemen's club, where we were discussing Wittgenstein over a game of backgammon."
Scully: "Mr. Simpson, it's a felony to lie to the FBI."
Homer: "We were sitting in Barney's car eating packets of mustard. Happy?"
Mulder: "Wait a minute, Scully. What's the point of this test?"
Scully: "No point. I just figured he could stand to lose some weight."
Mulder: "His jiggling is almost hypnotic"
Scully: "Yes, it's like a lava-lamp"
Homer: "I saw this in a movie about a bus that had to speed around the city, keeping its speed over fifty, and if its speed dropped, the bus would explode! I think it was called 'The Bus That Couldn't Slow Down.'"
Mulder: "Are we alone in the universe? Impossible. When you consider the wonders that exist all around us... voodoo priests of Haiti, the Tibetan numerologists of Appalachia, the unsolved mysteries of Unsolved Mysteries... The truth it out there."
Also, this bit always cracks me up;
Mulder: "Agents Mulder & Scully...FBI"
:lol
