Christopher Plummer won the Oscar for Best Actor in a Supporting Role at the 84th annual Academy Awards Sunday night for his role as a terminally ill widower coming out as a gay man in the film Beginners.

Plummer gave one of the most memorable (and hilarious) acceptance speeches in Oscar history. Read his full speech below:

You're only two years older than me, darling. Where have you been all my life?

I have a confession to make. When I first emerged from my mother's womb, I was already rehearsing my Academy thank-you speech. But it was so long ago, mercifully for you I've forgotten it.

But I haven't forgotten who to thank. The Academy, of course, for this extraordinary honor, and my fellow nominees: Kenneth, Nick, Jonah, dear Max. I'm so proud to be in your company.

Of course, I wouldn't be here at all if it wasn't for Michael Mills and his enchanting film 'Beginners.'

And my screen partner of course, Ewan McGregor, that superb artist who I would happily share this award with if I had any decency--but I don't.

All the producers at Olympus films, especially Leslie Urdang and Miranda de Pencier, and all the people at Focus for their tremendous generosity and support. And not to mention my little band of agents provocateurs: Lou Pitt and his wife Berta, Carter Cohen, Pippa Markham and Perry Zimel, who've tried so hard to keep me out of jail.

My daughter Amanda, who always makes me proud. And, lastly, my long-suffering wife Elaine, who deserves the Nobel Peace Prize for coming to my rescue every day of my life.

Thank you so much.

At 82 years old, Christopher Plummer is the oldest Academy Award winner in history. But the veteran actor was up against some pretty stiff competition: Max von Sydow (for Extremely Loud and Incredibly Close), Kenneth Branagh (My Week With Marilyn), Nick Nolte (Warrior) and Jonah Hill (Moneyball).
