Charity event, Comedy club: This is a great event held once a year at Second City, downtown Toronto. It's 24 hours straight of improv comedy (yup, bar is open for 24 hours!) in support of The Therapeutic Clown Program at Sick Kids Hospital. Each year, local Toronto personalities (David Miller, George Strop., etc) come out and particiapte. It's a really fun event for a great cause.
I've been twice in the last few months and had a blast both times. Haven't been to Yuk Yuk's lately so hard to compare, but my fav at the moment in SC!
