How I Met Your Mother is a US sitcom that runs Monday nights on CBS. In last night's episode (Season 4, episode 18 Old King Clancy) there is a Rush reference. Barney (Neil Patrick Harris), Marshall (Jason Segel - who also stars in I Love You Man) and Lily (Alyson Hannigan) were talking with Robin (Cobie Smulders) about a sexual experience she had with a Canadian celebrity who got her back to his place by showing her a very unique collection but ruined the moment when this celebrity wanted to do a weird Canadian sex act. Over the course of the episode, the characters tried to guess the celebrity, the sex act and the items that this celebrity collected. At one point, Lily guessed anyone from the band Rush, a montreal meat pie and superhero lunchboxes. You can watch the entire episode online at this link (the Rush reference occurs at about the 16:40 mark). Thanks to Riff Raff for the heads up.
