   Hank Ledger · Lead AnchorThe song came from The Fault in Our Stars. I haven't seen it. I haven't seen any film. I assumed they were all short.

    Dale Bearman · Chief Skeptic & ContributorNor have I, so we're both getting this one through the radio. Charli told the crowd, so you have her to thank.

    Hank Ledger · Lead AnchorSo we have a friend to thank, then. I'd have said no. Which is why nobody dares me.
