Seriously, if this video doesn't make you smile, there is something wrong with the feelings part of your brain. Seriously, we went into this like "no dancing pony can make us smile, cuz' we're hard like that," but we didn't last long, no matter how much we thought about the end of 'Marley & Me.'

We blame the unsinkable combination of ponies and Fleetwood Mac. If you don't like Fleetwood Mac (you monster), we have good news -- you can make your own pony video!

Thanks to the genius ad wizards working for Three (a British mobile company), you can virtually dress up a pony in ridiculous costumes like it's a paper doll, and then it dances around to a song of your choosing. We came up with some different combinations. You know, for research's sake:

Rave Pony
