Post any category and I'll post my Top 3. If I don't know it (Fire Emblem Thracia 776 characters, Hungarian kings), can't name 3 (Songs by Adele, U.S. governors), or it's nonsensical (atoms in the universe, hair on your cat's body), I'll do a different Top 3 instead.
One category per user until I post my Top 3 (or pass), then you can post another category.

Oh, I am one yet many.
