- With giant yellow donuts:
Mmmm.
Doooonuts.- With "lots" and "lots" of "hearts."
"Perfect."
- By planning ahead.

Way, way, WAY ahead.
- By stressing the importance of family:

Actually, Darth Vader fighting Luke in honor of an impending marriage is kind of awesome. Let's just hope your in-laws have a good sense of humor.
(And make sure the baby shower cake looks like this.)
- By comparing your new life together to violently killing things:
"Here we see the groom taking aim at his violently diarrheatic bride-to-be."Ah, young love."
(Don't worry, kids; he's only going to tranq her 'til the green diarrhea stops.)
Or, of course, there's always the old standby:
- A syrupy sweet public display of affection
that'll leave your guests sick to their stomachs:
"Dude. Some of us are trying to eat over here!"
Thanks to Sandy S., Abbey A., Matthew W., Rachel C., Naomi H., & Jule Ann H., who are so syrupy sweet they should be on a stack of pancakes.But I am not advocating cannibalism.
