You have to improvise a lot over the Christmas period. The turkey's burnt to a cinder – let's just eat that last packet of Bernard Matthews Turkey Ham. Nan's bought you the vilest pair of socks you've ever seen – "Oh thanks Nan, just what I needed. Exactly the ones I was after too." So why not get warmed up with an intro to creative lying at Crimbo Impro. The Funny Side's resident man of mirth, Dave Bourn, will lead you in some warm up activities and then go on to some of his favourite improv (reindeer) games. There'll even be a break for tea and mince pies. There's no better prep for the holidays. Over 18s only. Valid ID required.
