#30: Grandpa’s Sausage
Why does the internet continue to ruin my favorite childhood shows? First, The Fairly OddParents, now Hey Arnold! I’m starting to think no animation show is safe from the dirty minds of internet users. Apparently, people really seem to think Grandpa Phil was a depraved man since this is the second time he appears on our list.

Much like other cartoon shows, Hey Arnold! fans also came up with all sorts of crazy conspiracy theories about the program. The most insane one claims that Arnold’s grandparents, Phil and Gertie, are his real parents, and since they had him at an old age, he was born with a few health conditions, like hydrocephalus – thus the shape of his head. The theory went as far as to say that his name came from a form of hydrocephalus known as Arnold Chiari Syndrome.
