Break out the maple syrup and don your Mountie hat: Canada's favorite teen-pop sensation, Robin Sparkles, will make her triumphant return to How I Met Your Mother on February 4th. This time, actress Colbie Smulders will be joined by a cavalcade of Canadian stars – including Rush's Geddy Lee, Alex Trebek, k.d. lang, Alan Thicke and Paul Shaffer – in a salute to their home country. The video above lists all the guests from the Great White North who are set to appear in the episode – and no, James Van Der Beek is not from Canada, but he does play Sparkles' flaky ex-beau, Simon, which counts for something.
