The existence of Robin's alter ego, Robin Sparkles, was first revealed in Season two's Slap Bet, when Robin refused to go to an event at a mall and also refused to reveal why. Due to Robin showing shame at the mention of why she disliked malls, Barney thought that Robin had been involved in porn. Marshall suggests that she hates malls because she had once gotten married at a mall in Canada, when confronted about this she went along with the story of having been married rather then reveal the truth, going so far as seamlessly inventing details of the band and the catering.
