Mahou Sentai Magiranger is at times unabashedly silly and goofy, taking advantage of its magic motif to great comedic effect.
The sequence when Kai and Houka first realize that they have swapped bodies. The capstone? Tsubasa grabbing Mandora Boy to stun everyone so they calm down, and the very next thing we see is Mandora Boy in the corner, sobbing.
The scene begins with Kai (in Houka's body) entering completely oblivious to his situation until his siblings begin spotting mannerisms unique to Kai and not Houka. Houka (in Kai's body) comes flying in moments later in a panic. The two start piecing things together, resulting in a Crotch Grab Sex Check of utmost hilarity.
The first appearance of Mandora Boy, when the siblings are tidying up the Magic Room. He screams when pulled out, causing everyone else to scream and collapse...except Tsubasa, who had headphones and didn't hear a thing. He gives everyone a "What the hell...?" expression when he sees them collapsed.
From Stage 10: Makito's leading a round of towel rubdowns with Kai and Tsubasa when the girls pop out from the door. Makito calls them out to join - and Urara's jumping at the chance.
