Quite simply, The Big Butt Book ($40) is a book of butts. There is something about butts, bums, tushies, derrieres, that we simply can’t get enough of. The Karma Sutra told us how to spank them, Italians touch them for luck before placing bets, and Americans are having them cosmetically enhanced at an alarming rate. There exists an almost slavish devotion for butts, particularly big ones, and this is a celebration of the greatest big butts through time. From Aphrodite in ancient Greek times to Jennifer Lopez, big butts rule ok.
