he has the comedy central roast of bruce willis on sunday night, and he's the host of the show "roast battle" on that network too. "roast battle season 3" premieres tuesday. this is a fun show, a one on one insult match, comedians go back and forth on stage trading brutal blows about each other. comedians are all adults but we thought it might be fun to try this same idea out with kids. so we sent jeff out on hollywood boulevard to meet some kids, to pair them off and teach them to insult each other. >> happy summertime, you guys ready to roast? >> yeah! >> when i was a kid i got bullied. only way i could stop the bullying was to roast the bully back. you guys want to learn how to roast each other? >> yes! >> who wants to go first? come out here, come out here, bring your brother. >> battle, battle, battle, battle! >> let's roast! >> boy, you're so ugly, hello kitty said good-bye. >> oh!
