You know which box.

But boxes aside, when it comes to artists hosting "SNL," Timberlake's credentials put him in a league of his own. Topping our picks for his top five Timberlake "SNL" sketches is the aforementioned "Di-- in a Box" skit and his "Single Ladies" routine with Beyoncé. Both became instant memes and inspired countless Halloween recreations.

And now we look forward to Timberlake's May 7 hosting gig with ...

Timberlake and Lady Gaga: As the musical guest, Lady Gaga will already be in the building, so why not throw them into a sketch together? We're not saying Lady Gaga begs for parody, but we are saying that arriving at an awards show in an egg does. Add in the meat dress and the motorcycle cover and I smell another "SNL" Timberlake meme on the Twitter trends.

"The Social Network": Who didn't love Timberlake as a smooth copy of Napster founder Sean Parker in "The Social Network"? We could definitely use a little more of Justin in the tech nerd role. MySpace jokes never get old.

NSYNCKOTBSB Tour: Every 26-year-old woman who used to be a 12-year-old girl would be in favor of an 'NSYNC reunion. But let's make it even better and add 'NYSNC to the upcoming NKOTBSB tour.

What role do you hope to see Timberlake take on in his next "SNL" hosting gig? Let us know in the comments!
