(Dylan is in his room, happy that he has successfully cleaned it)
Dylan: I cleaned my room!
(Dylan is then surrounded by a lot of money)
Dylan: And I won the lottery!
(Phineas and Ferb appear behind Dylan and take selfies with him)
Dylan: And Phineas and Ferb are my new best friends!
(Dylan is very happy that all of this is happening)
Dylan: It's like a dream come true!
Phineas: Well, actually, it could obviously be a dream.
Dylan: How do you know?
Phineas: First of all, we're not real people. Second of all, there might not be a chance of you winning the lottery. Third of all, there's no way you really cleaned your room.
(Scene changes to Dylan sleeping in his unclean room, indicating that the whole thing actually is a dream)
Dylan (in his sleep): Good point, man.
