The "Fat Abott" cartoon in South Park, is it inspired by a real cartoon in US ? - south park french

I wondered if "Fat Abbott" is a real equivalent in real life, or if you do not have the strange idea from the creators of South Park.

(I hope my question is simple to understand, I do not speak French and English fluently - present)
