J.D.: [v.o.] It's never fun being the fifth wheel, especially when one of those wheels is Elliot's boyfriend. Still, I had decided to take the high road.
Sean: Hey, J.D., is this regular? I asked you to order me a diet.
J.D.: That is diet.
[fantasy:]
Sean: I don't understand! I'm so careful about what I eat, I'm just keep putting on weight!
Elliot: It's all the regular soda, Sean! [kisses J.D.]
[reality:]
J.D.: Enjoy.
J.D.: [v.o.] [evil laugh] All right, that's enough.
