arshall and Lily are hosting 2009 Thanksgiving at their new apartment for the first time. Because Ted and Robin come through with what Marshall deems the make or break item for Thanksgiving, he shows his ultimate gratitude: he is giving them the fourth of only five slaps to Barney Marshall won in a bet with Barney in 2006. The terms of Marshall's gift: it must be done before sundown so as not to interfere with dinner, Ted and Robin can decide between themselves who gets to deliver the slap, and they will tie Barney down to a chair for the slap. Barney, who has always hated the anticipation of the slap as much as the slap itself, is hoping that time will run out as Ted and Robin discuss then argue over who deserves to deliver the slap more. Thanksgiving may end up being as bad for Lily, whose deadbeat father Mickey Aldrin, who has always disappointed her and from who she has officially been estranged for three years, shows up at their doorstep. Marshall tries to convince Lily to forgive Mickey, whose appearance may not have been totally by accident.
