some of those Spongebob episodes are funny as, especially on a Sunday afternoon after a weekend at a doof.
Thats basically what it is for most of the bronies I've asked. However, some take it to a whole different level, which borders on the completely obnoxious. Those are the folks that piss people off, by shoving it in other's faces. That being said, I did see one episode, and it was actually damn funny.
That being said, my system was well lubricated with liquid bread at the time.
