A Lie or a Confession

Offer up a short, one sentence synopsis of something that may or may not have happened to you.  The listener must guess if it’s a Lie or a Confession.  For instance:  when I was in school, I once jumped naked into the university fountain at the student center.  If they guess right they win.  Even better, if it’s a confession, you then tell the story and do some character development content.  Thanks to Tess and Heather at  WKFR, Kalamazoo, MI for this idea.
