Jimmy Kimmel's Christmas challenge: bringing bad Santa to YouTube?

You may know US talkshow host Jimmy Kimmel from his long-running "feud" with Matt Damon . He's also become famous for the YouTube challenges he issues viewers, asking viewers at Halloween to pretend they had eaten all their children's candy and then videoing their reaction. For Christmas, he's told parents to say they're giving their kids their presents early and then film them. The twist is that that the presents must be really bad – think a half-drunk bottle of juice or an overripe banana. The reactions are definitely worth watching. Witty stunt or cruel prank? You decide.
