Best friend's surprise party scheduled for night of Lost Series Finale. How can I convince his wife to change the date?

Yes, I’m doing this for selfish reasons, but my friend is just as much a Lost fanatic as I am. I know that as much as he would enjoy the surprise party, part of him would be aching at the knowledge he was missing the finale. Heck, his wife likes the show too; I think she didn’t realize the dates conflict.

The issue is that the surprise party is being held in a restaurant and I’m pretty sure the wife has already put down a deposit. And informed other guests of when to show up (this Sunday night).

So the question is: what can I do to change the date of the party? Technically, my friend’s birthday is Wednesday, but due to Jewish holidays, he’s kinda restricted in what he can do to celebrate. I think that’s why his wife got the idea to do a surprise birthday party a few days later.

What convincing arguments can I use when I call her and tell her what’s up? I can’t just not show up to the party, but I don’t want to miss something I’ve been waiting years to see.

I actually couldn’t sleep last night when I realized the dates conflicted.

And please, no comments about how “it’s just a show.”
