5. Sheldon and Amy agree not to exchange Christmas gifts, but do anyway.
With Sheldon’s disdain for the holiday season, Shamy initially agree to not exchange presents. However, irritated by Amy’s recent PDA at a Christmas tree lot, Sheldon decides the best revenge is to give his girlfriend the most thoughtful gift possible—and then make her feel terrible for not getting him one in return. Emotional revenge wasn’t as satisfying as Sheldon hoped, though, because Amy decided to bake sweets for her sweetheart, which defied their original agreement, too. (BTW: She got the recipe from his Mee-Maw!) These two really are meant for each other.
