Gonna have to rank reheated food like so: mac & cheese, Chinese, pizza. Both Chinese and mac & cheese have the capacity to taste better on the second day, but there's no such thing as leftover pizza that is better than it was fresh from the oven.
And Jeph, what's this blasphemy you're trying to sell about day-old fried chicken? I'm a black man, which of course means that I automatically know the proper way to eat fried chicken. If you ever find yourself with more fried chicken than you can eat, you don't refrigerate the rest, you share it with a brotha' who's still hungry.
