"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.
