Connor: Who would believe a combination bear, mushroom, and ATM machine?
Kira: Is it really any stranger than the things we've been fighting?
We can't forget the one ("Leader of the Whack") where an Applied Phlebotinum reverses the trio's personalities and turns Connor into a nerd, Kira into a dainty Alpha Bitch and Ethan into a Jerk Jock...
And Devin into a ladies' man... or, what Devin thinks a ladies' man is, at any rate...
During Part 2 of "Thunder Storm", the crossover with Ninja Storm, Cam, Hunter and Blake are inside the Abyss of Evil trying to get their Ranger powers back. They see the Samurai amulet:
The Trio snooping around Tommy's house. Conner decides to play around with a model T-rex skeleton. Ethan tries to warn him not to. His response:
Conner: Dude, the guy's a teacher, not... *flicks a switch revealing a secret door* Batman.
In the two-part opener, Ethan and the other soon-to-be-Rangers are looking for Kira. He grumbles that "it's not like she's going to fall out of the sky and land right in front of us". Cue Kira doing exactly that. Granted, it was because she fell into the villain's Portal Network, but you have to admit, the coincidence of that happening is very funny!
Ethan tries to invoke this again in the finale. It works.
After Elsa blows her cover, she and Tommy end up kung-fu fighting in broad daylight and in front of all their students. Just imagine walking between classes one day and seeing your principal and science teacher battling to the death.
