"This river I step in is not the river I stand in." That line will likely ring familiar to most Toronto folk who've crossed the Queen Street Viaduct heading east across the Don River. Added to the structure by Eldon Garnet during a renovation effort in the mid-1990s, its thoroughly Heraclitean sentiment is a little reminder of the flux that surrounds us regardless of whatever efforts we might make to suppress the passage of time. It also happens to sum up one of the dominant ideas that Toronto artist Flavio Trevisan explores in his latest show, "Museum of the Represented City."

This week in Toronto comedy we've got black comedians, white comedians and YouTube comedians — oh my! Add NAFTA-inspired warfare with an improv tournament, and you'll see why there are plenty of reasons to navigate Toronto's pot-holed roads in search of laughs.

Sometimes the world looks more interesting in the reflection of a puddle. After having a glance at some rather accomplished street puddle shots — no that's not an oxymoron — on Gizmodo yesterday, we thought it worth a perusal of the blogTO Flickr pool to see if any local photographers had been similarly inspired. Lo and behold, there were lots of puddle pics to choose from. And good ones, too. So, what else is there to say? Sometimes looking down can get you up. Lead photo by Anthony AA.

This week's line-up will make you want to be in two places at once. From the casual brilliance of Jeff Leeson to the captivating stage presence of James Hartnett, Toronto's comedians will give you a reason to brave the cold.

What We Talk About is a new monthly lecture series that combines the joy of learning with the pleasures of alcohol. On Thursday night, over 40 curious-minded Torontonians gathered at No One Writes to the Colonel to listen to a group of informed and engaging speakers and enjoy a couple pints in the process.

Led by Alicia Merchant and Peter Merriman, each installment of What We Talk About has a theme and features experts from a variety of disciplines. The inaugural event's (very appropriate) theme was "Firsts" — the first carbon neutral neighbourhood, the first novel by Judy Blume, and the first slasher movie. There was a little something for everyone.

The Toronto Liberty project launches tonight with an exhibition that, according the event's Facebook page, promises to show you the city "like you've never seen it before." The new initiative presented by 44 Wide is made up of a group of Toronto photographers who are looking to change the landscape of the photo community in Toronto.
