There actually are some! Let's share them here. :)
For example! It's actually a slightly weaker entry in the HISHE series (which, over-all is pretty great), but the ending song easily makes up for that in the sheer awesome that it brings. I really want them to do a 'full' version of that doofy parodic ending song like their Zombie Song from their Resident Evil parody, though I suspect that this one will be a little harder.
Anyway, share away!
