Sonic the Hedgehog: Look at this, I took nine million steps today.
Dr. Ivo Robotnik: I was spitting out formulas, when you were spitting up formulas.
Tom Wachowski: I was breastfed, actually.
Dr. Ivo Robotnik: Nice, rub that in my orphan face. (00:30:15)
Dr. Ivo Robotnik: You know what's hard about being the smartest person in the world?
Agent Stone: Everyone else seems stupid.
Dr. Ivo Robotnik: Stupid, yes! Way to go! you got that one. (00:34:23)
Dr. Ivo Robotnik: I'm sorry, Mister...
Tom Wachowski: Wachowski. But everyone calls me Tom. Except my dentist, he calls me Tim. But it's gone on for so long that it would just be weird if I corrected him. (00:28:49)
Tom Wachowski: Why do you keep calling me Donut Lord?

Tom Wachowski: Again, fair. (00:26:27)
Dr. Ivo Robotnik: Eeny, meeny, miny... mayhem! (00:54:01)
Tom Wachowski: Hey. So, what's this next planet you're supposed to go to like?
Sonic: It's no Earth, I can tell you that. There's no people, just breathable air and giant mushrooms and stuff.
Tom Wachowski: Well, look at it this way. At least you won't be the only "fun-guy."
Sonic: No. Don't ever do that again! (00:49:46)
