Even though this is a comedy, you can't help but be creeped out by the still images. The way that they're all stretched and we have that scary music playing, makes this unintentionally scary.
Yeah, the vampires in this episode are all wearing obvious joke shop vampire teeth, but somehow this makes it all the more scarier. Who would've thought crappy looking joke shop teeth would look scarier than realistic looking vampire teeth in movies.
I remember when I saw this on TV before going to bed and I was scared to go to sleep because I was worried that the vampires would kill me as I slept.
I'm okay now, but that episode is still quite scary.
