This is the only time in the series that Dr. Drakken appears without Shego.
According to the show's staff, the reason Shego wasn't in this episode was because she had to attend a wedding.
Ron: (to Kim) If I said yes... would you let me do my Mad Dog routine?
Kim: That's not a good reason for me to say yes.
Ron: I know.
Kim: Because you're my best friend. That's a good reason.
Ron: Boo-ya! Mad Dogs lives! (barks and howls with joy)
Mr. Possible: Where's Drew? He was supposed to be here a half-hour ago.
Chen: I knew he wouldn't come through with dates for us.
Ramesh: What do you expect? He can't even come through with a date for himself.
Ron: (after Rufus has licked banana foam off Bonnie) You don't deserve to be kissed by a naked mole rat!
Dr. Drakken: There's no way I could be expected to conclude that my arch nemesis is the daughter of a guy I went to college with!
Kim: (to Ron) There's plenty of teams and clubs out there. You could join... the Mathletes!
Ron: Yeah, right! I can't get in that kind of shape!
Ramesh: Where did your daughter learn to kick bottom like that?
Dr. Possible (Dad): Cheerleading.
