The new 'face' of Little Debbie snack cakes appeared with Jimmy Fallon and...wow

Comedian Will Ferrell's "Tonight Show" appearance to promote his new movie "Get Hard" started on a strange note and just got "curiouser and curiouser."

Just a day after appearing on David Letterman's show dressed as a leprechaun, Ferrell walked on stage for an appearance with Jimmy Fallon dressed exactly like "Little Debbie," the iconic character seen on the boxes of the popular snack cakes.

Ferrell insisted that Fallon not refer to him as "Will" but as "Little Debbie."

Over the course of the 7:30 interview, Ferrell's movie was barely mentioned. Instead, viewers were treated to a strange series of events, including Fallon being goaded into reading some sketchy promo copy the snack cake company would probably never approve.

Ferrell also sang something he claimed to be the "Little Debbie" jingle.

And then, there was the very odd, blindfolded taste-test challenge that Ferrell put on himself.

"I love them so much, if I close my eyes and eat something, I can tell you if it's a tasty 'Debbie Delight' or a plain baked potato."

Fallon was ready for the challenge and produced a plate with a baked potato and a snack cake.

Spoiler alert: Ferrell succeeded in identifying the Little Debbie cake.
