[1] Since Lily has reformed her ways, Ted plans a repeat of what broke up his relationship with Robin, involving champagne and a wedding ring.
[2] Much to their surprise, the plan results in the couple mutually surrendering to the idea of matrimony, and after they announce it in the bar, Lily agrees to break them up properly.
Lily has a plan to remind the couple of their four biggest arguments: dirty dishes,[3] Barney's ex-girlfriends, Stormtroopers, and a Canadian-American war.
She contacts Robin's friend, Alan Thicke, to meet the couple at their usual diner, along with one of Barney's insane one-night stands, Meg (April Bowlby), a passing actor dressed as a Stormtrooper, and a busboy carrying dirty dishes.
Although Robin says it might take Barney a while to recover from the breakup, he appears as his old self, catching enticing glances from most of the women in the bar and declaring "Daddy's home".
Club, though skeptical of fat suits for what he describes as the Norbit Rule, felt it was worth it thanks to the "I'm my own wingman tonight" quip, and thought everything Alan Thicke related was funny.
[5] Joel Keller of TV Squad notes this episode makes particularly effective use of Future Ted (Bob Saget) and the exaggerations and distortions he lends to the story, from fat Barney and haggard Robin, to the video flying magically into the player.
