Late night talk show host Jimmy Kimmel has a new challenge for parents. He is asking parents to ‘Silverstone’ their kids. The reference is to an infamous viral video where actress Alicia Silverstone pre-chews her child’s food. She then feeds it to him like a bird. Spitting it into his mouth. Kimmel is now challenging parents to present pre-chewed food to kids and post their reactions to YouTube. The results are hilarious.
