Leonard: You've come to a giant metal door.
Sheldon: I check the door for traps.
Leonard: There are no traps.
Howard: I use my wizard eye to see what's on the other side of the door.
Sheldon: Hey, that's sort of like how you used a doorbell camera to spy on your fiancee.
Raj: No, it's nothing like that.
Leonard: Your wizard eye reveals a monster.
Howard: Oh. Is it alone and unloved?
Leonard: I guess.
Howard: I open the door and say, "Hey, Raj."
