Power Rangers refrences/jokes in other TV Shows

So, I'm working on a little project and thought I could use a bit of help from some people. Does anyone know of any in jokes and/or refrences that were made toward Power Rangers in other TV Shows? Like the episode of Seinfeld where George had a Red Zeo action figure, or the episode of Supernatural that had Dean say "so you're Gods personal little Power Rangers?". Even spoofs to the show are good, like the Animainiacs episode.

Also, if you remember the season and episode title of those shows, please list them.
