Seth Rogen and Jimmy Fallon donned their best 1980s lounge jackets to do a very special set of stand-up comedy on the Tonight Show on Thursday.
Standing in front of a traditional comedy club brick wall, Rogen and Fallon delivered jokes written by young children, and the comedic stylings of grade-schoolers proved to be pretty amazing (albeit unintentionally). It was basically the stand-up comedy version of Fallon's awesome "Kid Theater" sketch.

"What did one lawyer say to the other lawyer? Answer: We're both lawyers," Rogen said, kicking off his set with a joke written by a 9-year-old named Izzy.
Fallon started his bit with a joke, submitted by a 10-year-old named Erin: "You guys hear about the two antennae's that got married? It was a nice ceremony but the reception was amazing."
While a lot of the jokes were basically the kind you'd read off a popsicle stick, or heavily influenced by the parents of the kids who submitted them, the way Rogen and Fallon dove into their washed-up open-mic comic personas made the whole thing come together hilariously.

While sitting down with Fallon before the sketch to promote his upcoming comedy Neighbors 2: Sorority Rising, as well as his new AMC series, Preacher, Rogen took a trip down memory lane with a look at some of his own youthful stand-up comedy.
Fallon played a clip of Rogen, who appeared to be in his teens, delivering a hilarious bit about having to recite the alphabet song while looking up names in a phone book.
"That dates the bit," Rogen joked after the clip. "The fact that I was dealing with an analog phone book at that time, it anchors the bit in a really dated time."
Neighbors 2: Sorority Rising hits theaters Friday, while Preacher premieres May 22 at 10 p.m. on AMC.
