Will I Burn In Hell for My Roast?

I've been asked to deliver a roast at a very good friend's wedding rehearsal dinner tonight and I'm a bit nervous about it. See that line between good-natured humor and offensive/grossly inappropriate snark is something that's been troubling me. So I ask the reader(s) of this blog (but not you, Mom, I know what you'd say) if you think this joke goes too far:

"How many of you know the incredibly sweet story of the way Justin proposed to Olivia? Well, briefly, it involved planning a surprise trip to Italy, presenting her with an heirloom engagement ring, and proposing to her at her childhood school. It was an unbelievable testament of his love to her. But Justin, fyi, in the past all a fella needed to do to get Olivia to say 'yes,' was to give her a cheap bottle of wine and a burrito."

Too rough? Please feel free to comment...

And truly heartfelt congratulations to my friends Olivia and Justin on their wedding this weekend! They are a gorgeous couple in every way, and I wish them an amazing life together.
