Totally Spies! - At one point, when the kids get captured behind a locked door, Timmy and the kids are thinking of a way to get out, and Betty suggests using a can opener to unlock the door. Ivan asks her how is a can opener going to unlock the door. Betty then opens her mouth, only to say "Good question. I don't know!". This is a reference to the Totally Spies! episode "Totally Busted", where at one point, Sam (voiced by Betty's voice actress, Jennifer Hale), planned to open a back door with a can opener, although it's never revealed how she did it.
