So, you don't know everyone in your party very well, what should you do? Schedule a Lie Detector activity to get to know everyone on your stag weekend. Get together and make up a list of questions about old girlfriends, his future wife, his "past experiences."
You're the ones who know him best, so use your imaginations and come up with some zingers, then see how well he performs when he's wired to a polygraph. The Lie Detector is sure to deliver laughs and memories for your Budapest bachelor weekend!
