Huh, I actually hadn't seen that before!
It was on Fox Kids and it wasn't Power Rangers. That's probably why.
GRRR! I respect Power Rangers and their larger than you think fan base, but I ALWAYS hated the fact that they made it the only thing on the network. I mean, I LOVED stuff like Bobby's World, Eek The Cat, The Tick, Mad jack the Pirate, 1996 Casper, Oggy and the Cocroaches, Ripping Friends, Space Goofs, Toonsylvania and stuff like that... once they weren't getting Power Rangers ratings, even ones that were popular, they'd kick'em off the line up.
But the Mr. Potatohead show was great. It had these great inside jokes about network notes. I remember one episode Mr. Potatohead was trying to do a western, and the network guys were complaining about the prospect of gunplay, and Mr. Potatohead argued with them, and they refused. Then they did the show, and the network guys said "You can't have a Western without a gun fight!" Then there was a bit where they forced his show to be educational... so he does this super hero show where he defeats the badguy by awkwardly singing about the Pythagorean Theorem... And the Sweet Potato character was performed by Debra Wilson who'd later go on to MadTV... great stuff. I wish more people saw it.
