Time Out says
The up-and-coming improv-comedy destination Reckless Theatre presents its take on the omnipresent holiday parable. (If you think you’ve seen enough interpretations of the ghosts-change-a-grinch tale, think again.) Here’s how it works: For each of the three performances, a different improviser plays the role of Scrooge, and while the rest of the cast knows their lines, Scrooge doesn’t. If that sounds like a recurring nightmare from your drama-club days, well, meet the Ghost of Christmas Past, my friend.
