Jimmy Fallon and Justin Timberlake made adorkably pubescent camp memories on The Tonight Show last night. Chumming it up as brace-faced BFFs, the two scream-sang Third Eye Blind’s “Jumper” and talked a lot about Weedwackers and tiny chunks of hot dog. (It’s as goofy as it sounds, and the best part is they break character almost every ten seconds.)
