My favorite part was in Clan of the Cave Bear (I think,) where Jean Auel took a page and a half to describe the ***SPOILERS FOR, Y'KNOW, YOUR APPETITE*** lichen-covered, S-shaped member of a wooly mammoth.
It was required reading in my sixth grade English class, though I'd already read it two years prior. Reading it on my own was fine, because I was being mature and transgressive! Reading it again for school was kinda creepy.
