Top 10 best/worst - initial ideas

I have a few ideas for this but ideally I want to do something humerous... Most credit should go to my collegues at Jigsaw over Christmas for helping me make this list!

1. back-handed compliments (you've got a pretty face, but theres alot of it)
2. pets wanted as a child (giraffe, puppy, unicorn)
3. breeds of ducks (I love ducks, dancing ducks, midnight ducks, puddle ducks... the list goes on)
4. imaginary friends (a superhero, a boring man in a suit, alligator who lives under the carpet)
5. surnames (poohead, man, hitler)
6. numbers (thirteen, swentysphive)
