<P> While Barney flies to Robin's hometown of Vancouver, British Columbia to interview her ex-boyfriends, Ted asks Jeanette about her pulling the fire alarm to force them to meet, and she says it was because she "couldn't stand the idea of not meeting you", leaving Ted once again charmed at her . Marshall makes Ted realise that the fire alarm is actually a smoke detector, meaning to set it off, she would have to start a fire; Jeanette admits to this but still, Ted finds it charming . Meanwhile, Robin's co-star on the "Sandcastles in the Sand" video, Simon, reveals to Barney that a MuchMusic documentary show about musicians' lives off the stage, Underneath The Tunes, discussed Robin's career in an episode . </P> <P> Marshall gets increasingly irritated that Ted has found Jeanette's behaviour attractive, and that their "destiny" was forced . Barney returns with a copy of the Underneath The Tunes episode and shows it to Ted, Marshall, and Lily . Using interviews with many Canadian celebrities, the documentary depicts a picture of Robin's musical career different from that she described in Slap Bet . She originally described "Let's Go to the Mall" as a minor hit, and "Sandcastles in the Sand" as her artistic follow - up and a total flop, possibly to stop the group finding out more . However, the documentary reveals both were hits that "went Maple", but her musical career declined in the mid-1990s . Dissatisfied with the bubblegum pop - star persona that made her popular, Robin reinvented herself as a grunge singer named Robin Daggers . She made a music video of a song, "PS I Love You", that her record company refused to release . Robin's career ended after a disastrous 84th Grey Cup halftime show at which she revealed her new persona as soon as she appeared on stage . When the show speculates that Robin's occasional costar Alan Thicke is the subject of the song, Barney visits him and violently demands the truth; Thicke easily defeats Barney and denies that he was the song's subject . </P> <P> The badly bruised Barney returns to the others, claiming that he fought Thicke to a draw . The situation forces him to admit that it was easy to end up obsessed over romantic interests . Robin comforts him and reveals that the "PS" in the song was Paul Shaffer . Barney admits that his jealousy made him a total "Dahmer", but Robin assures him, saying he is her "Dahmer", making him a "Dobler". Ted still insists that his and Jeanette's relationship is likewise, frustrating Marshall, but he is angered when Lily admits that their chance encounter was not chance at all; she had seen him during the freshman orientation and, under the pretense of needing someone to fix her radio, knocked on all doors in Marshall's dorm building until she found him . Despite it being creepy, Marshall slowly finds it charming and concedes to Ted . When Ted is with Jeanette and finds her copy of One Hundred Years of Solitude, he learns that the book was bought within minutes after he bought his copy . Jeanette admits that she has been stalking him since he appeared on the cover of New York magazine in fall 2011 . Even still, Ted finds her confession charming and the two start kissing passionately, as Future Ted tells his kids that Jeanette was the last mistake he made before he met his future wife . </P> <P> The episode describes the ultimate decline of Robin's career as Robin Sparkles, who first appeared in the season 2 episode "Slap Bet", returning in the season 3 episode Sandcastles in the Sand (also the name of Sparkles' music video) and the season 6 episode Glitter . Series co-creator Craig Thomas said it would be a "fitting end" to the show tackling Robin's music past . </P>
