The entire script to Clue. Including whole exchanges between Colonel Mustard and Wadsworth sometimes. The ones I end up hearing in my conversations a lot are:
Miss Scarlet: “Why is the car stopped?”
Prof. Plum: “It’s frightened.”
Col. Mustard: “Are you trying to make me look stupid in front of the other guests?”
Wadsworth: “You don’t need any help from me, sir.”
Col. Mustard: “That’s right!”
Wadsworth: “Well, to make a long story short—”
Col. Mustard: “Too late.”
Mr. Green: “Who would want to kill the cook?”
Miss Scarlet: “Dinner wasn’t that bad.”
Prof. Plum: “There’s no need to shout.”
Wadsworth: “I’m not shouting!” [pause] “All right, I am. I’m shouting! I’m shouting! I’m shou—” [thump!]
Cop: “This man is drunk. Dead drunk.”
Miss Scarlet: “Dead right.”
Mrs. White: “What do you mean, don’t deny it? I’m not denying anything.”
Wadsworth: “Another denial!”
Col. Mustard: “There’s still one thing I don’t understand.”
Mrs. White: “One thing?”
Wadsworth: “And monkey’s brains, though popular in Cantonese cuisine, are not often to be found in Washington, D.C.!”
Mrs. White: “Yes, I did it. I killed Yvette. I hated her… so much. It – it – the fee – flames – flames… on the side of my face, breathing – breathle – heaving breaths, heaving…”
(Also, being a complete dweeb, I can’t help but inject a few Monty Python and the Holy Grail lines into my daily patter…)
