I did 2 truths and a lie for this lesson and it worked great. I let each student write their own 3 sentences with one being a lie. I put all of them in a bowl and chose one at random. The class was divided into five groups, each group with its own whiteboard. That student would read the three sentences and each group would vote for which sentence was a lie. If the group was right they would get a point. If the student was able to fool the entire class, meaning nobody guessed the lie, that students group would get 2 points. The winning group got a prize. It went great, attached is a sheet to write the sentences. Just print and cut it up.
