To try and help Ted, law student Marshall searches a legal database and he reveals 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 (one for the lie, two for being premature).
