Spongebob Squarepants 

A low quality cartoon idolized by 16 year old boys that wear 'My Little Pony' t-shirts.

It is hypothesized by many critics that SpongeBob Squarepants is the modern day equivalent of bloody fecal matter, yet a majority of people argue that bloody fecal matter is far more humorous.

I would rather shove a handfull of razors in my asshole and listen to Celine Dions entire compilation of music than to watch a single episode of SpongeBob Squarepants.
