40th Birthday Help

So I am having a dinner for my sisters birthday. First we are going to the spa and then meeting a 10 of her girlfriends and family for dinner. A suprise.
I was wondering if anyone had any cute things to do during dinner. Like a game or quiz that might be funny.

Any ideas?

You can do a how well do you know the person quiz. Make a quiz with hard questions and see who knows her the best.

How about getting one of those newspaper reprints for the day she was born? Here's a linkNYT
And that whole site has some fun ideas:
