Everybody knows that laughter is the best medicine. But, if you laugh for no reason, you might need medicine. Therefore you should probably find yourself a real reason to laugh before people start suggesting you get help. Thankfully Clapham Fringe has just the ticket with the Clapham Comedy Club Showcase. With some special guest comedians and MC Sion James, they'll be justifying your cackles in no time. Previous guests have included Micky Flanagan, Stephen Merchant and Milton Jones amongst others, so you never know who's gonna turn up. Please arrive on time as latecomers may not be admitted.
