Actually, this isn’t totally wrong, even if the comic is obviously a comic.
Fat people (at least, the ones who aren’t bedridden) DO tend to be pretty significantly stronger than skinny people that aren’t doing enough exercise, and it’s literally for this reason. Carrying all that fat around genuinely does provide some training.
Don’t get me wrong though, someone who’s doing proper exercise will obliterate both of them, but it’s still an interesting fact.
Fun fact, a Tesla spokesperson describing the car’s features was talking about how they wanted something on the car that didn’t make it to final release and said “But sadly we couldn’t get that law changed”, which does… kind of imply that they lobbied the regulatory bodies into allowing this piece of shit to exist.
