A riddle

Fiona: "Mommy how many bumps does a cannibal have?"
Me: Hmmm, this must be some sort of riddle... "I don't know sweetie, how many bumps does he have?"
Fiona: "No, I'm asking you, how many bumps does a cannibal have?"
Me: "Bumps? A cannibal?"
Fiona: "Yes, you know, a cannibal! One bump or two bumps?"
Me: "Ohhhhhhhh. A CAMEL!"
Fiona: "Yes! A cannibal!"
