It’s Not You, It’s-A Me, Mario. Watch the “Seinfeld” and Mario Mash-up You Didn’t Know You Wanted.
If some theoretical physicists are right and the universe is really a multi-verse. And if the show Sliders is right and that multi-verse is full of alternative versions of our world, then there has to be a world where the characters from the Mario Brothers-iverse live in the Seinveld-iverse. It's science!
I look forward to seeing Jerry dodge Spinies from the Lakitu while he chases Newman through World 4-1.
