She's already accepted an Oscar - sort of
Oh wow...I just realized that when Meryl Streep accepted her best actress Oscar for "Sophie's Choice" in 1983, she was pregnant with Mamie. How cool is that?
If Mamie ever wins her own Oscar, she can get up on stage and say "Hmmm...it feels like I've done this before."
NOTE: "Sophie's Choice" was released in 1982, but the awards ceremony was of course held in 1983.
