Missed out on the Edinburgh Fringe? No problem. You can experience practically every single comic* from this year's festival in just eight or so hours at this one-day mini-fest. The huge line-up will be revealed on the day, but past acts include Al Murray, Daniel Kitson, Bridget Christie and Sara Pascoe. It's all organised by comic Michael Legge, and proceeds go to MIND, the mental health charity.
*Rough estimate.
