Marshall: I vow to always sit next to you and hug you, even if you're covered in vomit, Whether it's yours or Marvin's, or in the case of what came to be known as Spew Year's Eve 1998—My own.
Lily: I vow to stop getting so angry…
Marshall: Ooh, I just thought of another one.
Lily: …when you interrupt me.
Marshall: Mine was to interrupt you less, so that's good. I vow to finally stop petitioning Paul McCartney to let Weird Al record 'Chicken Pot Pie' to the tune of 'Live and Let Die.' It's over. I'll let it go.
Lily: I vow to cry less during this pregnancy.
Marshall: I vow to cry less during this Vikings season.
Lily: Mm, with that secondary, I wouldn't make that promise.
Marshall: I vow to keep at least 80 percent of these vows.
Lily: That seems high.
Marshall: And I vow to keep updating them as we go. Because one set of vows, it can't cover a lifetime of growing and changing with you, of raising children with you, falling more and more in love with you every day, Lily Aldrin, which is what I vow to do for the rest of my life.
