Dorcas: What would you buy if you were bored?
Neville: Uh... a jar of calf's foot jelly.
Gonzo: I wonder how far you could plummet before you blacked out.
Kermit: Uh, don't try it, Gonzo. We need you for this movie.
Gonzo: Sure is tempting.
Fozzie: Uh, excuse me, Mr. Holiday, sir. Would you let Kermit go? If you hold him too long, he'll just give you warts.
Dr. Bunsen Honeydew: I suggest we jump.
Fozzie: Are you crazy? That's at least a hundred feet.
Dr. Bunsen Honeydew: I didn't say it was a good suggestion.
Beauregard: Maybe we could jump part-way.
Statler: Hey, Waldorf. Wake up. Here come the bikinis.
Waldorf: Oh, boy! We better synchronize our pacemakers.
Truck Driver: What are you doing here?
Oscar the Grouch: A very brief cameo.
Truck Driver: Me too.
Kermit: Piggy? Piggy, you're overacting.
Miss Piggy: What?
Kermit: You're overacting. You're hamming it up.
Miss Piggy: I am not! I am trying to save this movie.
Kermit: Yeah, well save your performance instead.
Kermit: I hate to be rude, but we're trying to do a movie here.
Beauregard: Takes awhile to get to know the town.
Fozzie: How long have you lived in London?
Beauregard: All my life.
Kermit: How come you don't have an English accent?
Beauregard: Hey, I'm lucky to have a driver's license.
Beauregard: What's your room number?
Kermit: What?
Fozzie: I don't know, but we're on the second floor.
Beauregard: Oh, I'm sorry. I can only take you as far as the lobby.
Kermit: How are we supposed to cut through the bars if nobody brought stuff to cut with?
Floyd: I brought some hot mustard, maybe that will eat through the bars.
Sam the Eagle: You are all weirdos.
Gonzo: Stop the presses.
News Editor: Why? What happened?
Gonzo: I don't know. I just always wanted to say that.
Lady Holiday: Give Stanley a tip, Nicky.
Nicky Holiday: For complimenting you on your necklace?
Lady Holiday: No, because it's customary.
Nicky Holiday: I haven't any change.
Lady Holiday: Then give him something bigger.
Nicky Holiday: Bigger? I left my wallet at home.
Lady Holiday: You left your wallet in college.
Kermit: But... Nicky, why are you doing this?
Nicky Holiday: Why am I doing this? Because I'm a villain. It's pure and simple.
Fozzie: What does "BSC" stand for?
Kermit: I don't know.
Answer: As shown in Nicky's office, him and the models are professionals, judging from the different tools that they are using and a map of the Mallory Gallery. All they would have to do is watch and wait for the dogs to leave a specific area, and they would be able to get in because of how quiet they were while Kermit and friends were caught because of how much noise Animal made while trying to eat through the bars.
