(Krieger's lab, interior. It's full of weird shit, House is fascinated and nosey but trying to hide it. He and Krieger are smoking and listening to 2112 by Rush, "The Twilight Zone" is just starting.)
Krieger: I genetically engineered this stuff myself, do you like it?
House: (big inhale) Yeah...nice.
Krieger: It sometimes has a weird side effect though, it can cause alternate dimensions to open up.
House: (laughing uproariously) Oh, come the fuck on, I'm not high enough to believe that!
(A large green swirly portal opens up in the wall and Rick and Morty step out.)
Morty: Uhhh, uh, are w-w-we sup-uposed to be here?
Rick: Oh, damnit, no, Morty, we're not supposed to be in this uni-BURP-verse, it isn't even drawn in the same style! (distracted) hey, do you have Farewell to Kings? I love that album, put it BURP on after this one!
House: (to Krieger) can I buy some of that from you?
(about an hour later. Krieger, House and Rick have been joined by Dr. Evil, Dr. Forrester from MST3K and Dr. Venture. The lab now has the remains of several pizza boxes, part of a carrot cake and a mutated duck/lobster that is trying to leave without being noticed. Morty looks bored and stressed out.)
Everyone except Morty: (singing very loudly) FORGE A NEW REALITY, CLOSER TO THE HEART, CLOSER TOOO THE HEEEEEEAAARRTT!
Rick: (to House) You can't hit those high notes like Geddy BURP but you've got a great voice.
House: (a little taken aback) Thanks.
