During their visit, Fallon asked the duo about Honey Boo Boo's -- real name Alana Thompson -- latest hobby.
"I've heard you've been taking cheerleading," Fallon told the 8-year-old reality star. "It looks like she wants to do it right now," he added to Mama June.
Seconds later Fallon pulled out a pair of shiny silver pom poms from his desk and Honey Boo Boo and himself launched into a quick cheerleading routine.
The fourth season of TLC's Here Comes Honey Boo Boo will premiere Thursday June 19.
