At the end of the episode they were "filming" they ran a series of fake end credits that credited all the characters as themselves.
Scott: Now, you should never hit girls. But, considering she's a robot, well...
Tenaya 7: Boys always think they're so much faster and stronger then girls. (puts Scott in a half-nelson) Don't believe it.
Ziggy: Hey Doc, come out and, uh, help us show off some of the weapons.
Doctor K: Ranger Green, I'm busy synchronizing the energy matrix of three multi-dimensional bio-fields. Besides, I don't go out into the sun.
Ziggy: Sure you do!
Doctor K: Not possible.
Ziggy: Just once!
Doctor K: Never.
Ziggy: (holds up a bag of marshmallows) Mister Marshmallow?
Doctor K: Okay, one minute.
Summer: We don't just go out there and "do" stunts.
Dillon: Yeah. First, we learn how, so we don't break our necks. It all starts with some physical training.
Summer: Then they hook us up to a rig, so we can fly. And then we go out there...
Dillon: And break our necks!
Summer: No, we don't! 'Cuz we're careful. We're very, very careful.
