As a fellow comedian, with a moderately amusing T, I am learning funny isn't always the best way to go. Maybe there is a reason you need to go searching for ideas. I would just try to not be judgmental, which to me, an outsider counting the days kinda seems like. I would go more for a congratulations on your special day, maybe just even a really beautiful flowery store bought card that she can display at home for a while and simply enjoy the peace and beauty of. But I think is truly wonderful and thoughtful of you to want to recognize and celebrate your friend, really, your friendSHIP. Freud said, but where would you find such a friend? (ie who would listen to you as a therapist do) - you two are lucky to have found each other.
