"We're committed to promoting safe and inclusive learning environments for all of America's young people," Holder said. "And I'm proud to join Cartoon Network in calling on every student, parent, and educator to pitch in, and do their part, to speak up against bullying."

Gosselaar and Meyer play "underdogs" on Franklin and Bash, so its no wonder they would stand up for those less fortunate.

."The one thing we've always loved about the show is when we're the underdogs with our backs against the walls and we have to fight for the little man," Meyer told TV Guide in August.

Franklin and Bash airs on TNT at 10 p.m. ET on Thursdays.
