There’s just something about spring, apparently, that got everybody’s junk out of the trunk. Everywhere we looked last month, bottoms were popping up in campaigns like snowdrops. Here are a few of our favourites:

“Get your butt seen”
This campaign, for the Colorectal Cancer Association of Canada by Ogilvy Montreal, invited Ontario and Quebec residents to post pics of their posteriors on Facebook and YouTube, and remind their friends to get screened via Twitter and email reminders.

In through the out door
A perennial favourite, the inflatable Giant Colon is touring Ontario as part of the province’s “ColonCancerCheck” campaign. Recently spotted at Dufferin Mall in Toronto, the colon is adorned with over-sized polyps that would inspire anybody to get checked.

Nothing to see here
To raise awareness about sexually transmitted infections (STIs) for the Quebec Ministry of Health, Espresso Media and Cartier Communication developed an online concept to grab the attention of 15- to 24-year-olds. Called “Often there is nothing to see,” the wallpaper image of a young man’s or woman’s naked midsection is covered by the site content, which falls away when clicked to reveal a message about the invisibility of STIs.
