Brain Game: Buzzing with Excitement

Please say hello to my friend Greg, whose likes and dislikes will help you solve today's mentalfloss.com Brain Game Free-for-all Friday challenge. Good luck!

He'd ride a horse before getting on a bike.
And Greg would rather eat fruit than vegetables.

unicorn, dragon, mermaid
