Justin Timberlake continued his week-long residency on Late Night With Jimmy Fallon Thursday, and somehow after four nights he still makes for truly electric TV viewing. Promoting his much anticipated new album, The 20/20 Experience (out March 19), JT debuted a new track live and again delivered with a hilarious sketch alongside the show's host.

In the skit, above, Timberlake and Fallon played prepubescent teens at summer camp with a strange hankering for singing Toto's "Africa" a cappella—much to the dismay of their creepy counselor. BTW, this duo have freakishly awesome harmonizing skills.

JT also performed sensual 20/20 standout "Strawberry Bubblegum," busting out crazy smooth choreography with four backup dancers. Oh, how far JT's come since the synchronized boy band moves of his *NSYNC days. 

So, Mr. Timberlake, what's up your sleeve for tonight?
