Professor Proton: But I, I do, I do have a favor to, to ask.
Sheldon: Name it.
Professor Proton: Well, I'm, I'm booked to do a children's party tomorrow, and, um, frankly I, you know, I, I don't feel up to it.
Sheldon: Oh, you're not. You look awful.
Professor Proton: Thank you. Anyway, uh, I mean, you know my act better than anybody. I was, I was hoping that maybe, you know, maybe you'd fill in for me.
Sheldon: Are you saying that you want me to be Professor Proton?
Professor Proton: Yeah.
Sheldon: Oh, my. What an honor. Oh, this is like being asked to ascend Mount Olympus and dine with the gods.
Professor Proton: Or a Korean family in Alhambra.
Sheldon: But they'll know I'm not you. Should I call myself Professor Proton, Jr.?
Professor Proton: Sounds great.
Sheldon: So, in a way it's like I'm your son.
Professor Proton: What- Whatever.
Sheldon: Father.
Professor Proton: Sure, what the hell.
