4) People with tattoos are heretics... and they look damn ugly when they grow old.
5) Dante enjoys showing us her rotting cleavage.
6) Gluttony without the tattoo is a fat, hungry monster. Lust without a tattoo is probably a hentai character.
7) Wrath is now the Fullmetal Homonculus.
8 ) Envy is the source of our green eyed-monster.
9) When he stopped being cool, Envy just annoys the hell out of me.

19) The Rockbell house will someday be a refuge to orphans, single women and their babies.

31) Riza shoots because she cares.
32) Ed is short because his automail is too heavy. And damn, I know milk doesn't help because why am I still so damn short?!
