Another Loch Ness Monster Reference!

So I'm reading Breaking Dawn, the 4th and final book in the Twilight saga, when out of the blue there is a Loch Ness Monster reference! SPOILER ALERT!: Bella and Edward have a baby and the baby's name is Renesmee, but Jacob gives her a cute nickname, Nessie. Bella gets mad and says, "you nicknamed my daughter after the Loch Ness Monster!" Lol. I thought it was hilarious!
