Here's the story of a little Japanese boy who was scared of cacti/cactus plants, and how Den-O helped him overcome that fear. Be warned, the following vids contan major scenes of "AWWWWWWWWW"-type cuteness.

EDIT: Just saw Geki 12 - Man, that sneaky Mastah Elehan...
And HOLY SHIT RIO!!! Did you see what he did???
EDIT 2: Gekiranger cast on some quiz show (I think the name of it is "Time Shock" or something like that). Premise apparently is that they're shown two vids side by side which are identical except for some small detail. The contestant teams have to identify the differences.
