Round and round you go on the Darkmoon Carousel!
Patch 5.1 introduced the Darkmoon Carousel to the Darkmoon Faire. To ride the carousel you must purchase a Darkmoon Ride Ticket from Kae Ti, the NPC in the tent where the Carousel is. Take a ride on the carousel to gain the WHEE! buff. The buff increases experience and reputation gains by 10% and last an hour.
I took screenshots of me riding the different mounts on the Carousel.
