The episode led to two recurring jokes and storylines in the show: “Robin Sparkles”, Robin’s teenage pop star career, and the Slap Bet, in which Marshall slaps Barney at various points throughout the series. Ted, Marshall, Lily, and Barney find out that Robin never goes to malls and refuses to explain why. Marshall posits that Robin was married in a mall in Canada, because whenever asked about Canada, Robin only talks about her friend who got married way too young. Barney, however, believes that the secret is related to pornography.
They agree to a slap bet, where the winner of the bet slaps the loser as hard as he can, and appoint Lily as the slap bet commissioner. Ted begins to worry that Robin is married. Ted pesters Robin to reveal if she really got married in Canada.
After trying to avoid the issue, Robin tells Ted that she got married in a mall, after which her husband moved to Hong Kong without getting a divorce. Ted promises to keep it a secret, but tells the gang after Lily begs him. Law student Marshall searches a legal database, and tells Ted that there is no record of a marriage license for Robin in Canada. After asking her various questions about her wedding, Ted confronts Robin and she admits she is not married, but finds out that Ted told Marshall her supposed secret.
She is angry and tells him that she was testing him to see how long it would take him to tell the rest of the gang. She refuses to tell Ted the true reason she avoids malls. Marshall tells Lily that Robin is not married and Lily, as the slap bet commissioner, must allow Barney to slap Marshall three times.
Barney reveals that he has uncovered a video of Robin and asks her if the name ‘Robin Sparkles’ sounded familiar, which worries Robin. Ted tries to stop Barney from playing the video but Robin lets Barney play it. The beginning of the video shows Robin, dressed as a schoolgirl, seductively pleading with a teacher not to give her detention.
Barney, supposedly for the sake of Robin’s dignity, pauses the video and slaps Marshall. Let’s Go To the Mall”. Robin repeatedly sang the Canadian hit on a lengthy tour of malls around the country, causing her to develop a phobia of malls. Lily points out that Barney slapped Marshall without having won the bet and without the permission of the slap bet commissioner.
Lily gives Barney a choice: He can be slapped ten times immediately, or five times at any moment Marshall chooses. Barney picks the five slaps.
Robin tells Ted that she is glad Ted knows her secret now. They kiss and Marshall suddenly slaps Barney, proclaiming “That’s one”. The episode was originally titled “Robin Sparkles,” but the title was changed to “Slap Bet” in order to avoid giving away the ending.
