Comedian and TV host Howie Mandel reacts to YouTube star and friend David Dobrik coming to check on him after some fans on TikTok raised concern that he had been kidnapped. "The fact that I'm on TikTok should be enough of a clue that I'm not kidnapped. People are finding signs in every move I make," jokes Mandel. After a well-check from Dobrik, Mandel adds, "He came to rescue me. David Dobrik is like a superhero. I'm so neurotic, you know, with what's going on, masks and everything. And then, he shows up at my house to prove to his followers and the world that I'm not kidnapped. And I was so scared to come outside. Thank God I have all the equipment, which I've had for the last 40 years." Full interview airs Tuesday, July 28 on CBS.
