This one might be a little tricky, but eh?
John attended Brian Bragg's annual Christmas Party. John sat in a corner trying to be inconspicious when Bragg came over and began recanting one of his tall tales. "Why yes," began Bragg, "even my days as a younger man were filled with adventures. This beautiful white rabbit skin and that 14 point moosehead on the wall are both animals I shot when I was a lad of just 12. I got them both up in Canada during my July 4th holidays. Two summers later, I shot this beautiful bear you're sitting your feet on." John stood up and said, "Brian, I can't take your bullplop any longer! That story is obviously false!" What was the problem?
