If you told Johnny Carson 30 years ago that The Tonight Show would go on to become one of the internet's top content creators, he'd probably say, "I did know that. Also, what's the internet? Also, I'm off the clock, so get out of here." Yet here we are. Last night, Fallon had Samuel L. Jackson perform a slam poem about Boy Meets World because of course he did. It's bizarrely super-good. "That's some weird, wild stuff," Carson would say, before adding, "What is Boy Meets World? Also, how does one slam a poem? I need more details, seeing into the future, man!"
