Restaurant: Impossible has rebuilt some truly appalling diners and watering holes, but it may have finally met its match.

On last night's Tonight Show (September 23), Jimmy Fallon dreamed up a sketch in which his teenage self held a part-time job at Nickelodeon's infamous Good Burger. In case you've forgotten, the fictional fast food joint's signature dish was ineptitude served with a side of incompetence, and in the video above, Jimmy and Ed (played by the character's originator, Kel Mitchell) prove to be about as useful as a soaking wet fireplace.

"Welcome to Good Burger, home of the Good Burger. Can I take your order?" Kel offers in a sound byte that would send shivers up any fry-lover's spine. Jimmy and Ed earn their keep by squirting mustard on one ornery customer and breaking out into a spontaneous hip-hop performance after confusing "wrap" for "rap." Still, the real magic comes when Kel's former fellow All That cast member, Kenan Thompson, joins as a surly, wordy construction worker named Lester Oaks, who's jonesing for a quick bite.

"Now, I ain't got no time for your pleasantries, and your howdie-doody doodily-doos," he demands from Ed. "There's here's a serious matter that can only be rectified and reciprocated by you giving me a Double Good Burger and some frenchy fries."

Naturally, the order goes over about as successfully as a mesh canoe, but not before Lester accuses Ed and Jimmy of being "fuzzy nuggets." Quickly adding that gem to the insult-Rolodex...

The "Good Burger" sketch was originally featured on Nickelodeon's All That and spawned an eponymous movie in 1997.
