Follow these steps exactly and you can do it without it being illegal:
Go get some butter-flavored Pam (it HAS to be Pam, not the nonstick knock-off crap) and make sure that it's butter flavored. After you have been running your horse in a circle that's fifty feet in diameter (it won't work any bigger or smaller) for exactly 1 hour and 7 minutes go ahead and spray the Pam on its forehead. Place two slices of bread on its back and a slice of cheese on each one, then quickly search E-bay for horse tack and a piece called "Hitler's Halter". Buy it and make sure it comes in two business days or you HAVE TO START OVER. Once you have it, take a Polaroid picture of it on your horse standing next to a clown and put it in-between the two slices of bread (cheese side in, of course) to make a Polaroid grilled cheese sandwich. Mail this sandwich to Clinton Anderson, Australian horse whisperer. He will then reply with 4 letters that will be in your mailbox the following day. Open the one labeled "Hoof", shred the one labeled "Mane", burn the one labeled "Muzzle", and put the one labeled "Tail" in your left back pocket. The letter you open will have directions to the manhole nearest to your current location, and a guide through the sewers. If followed correctly you will arrive at DownUnder Horsemanship headquarters, if you make a single mistake you will be lost in the sewers and soon die of dysentery. Once at DownUnder HQ, climb the ladder in front of you and reach the Hall of Doors. Open the seventh door to your left and hand the letter in your pocket to the guard. MAKE SURE IT WAS IN YOUR BACK LEFT POCKET! If you reach for anything other than this pocket the guard has been instructed to kill you. He will grant you access to the Grand Master's Chamber, where you will receive a stick horsey as an apology for your lack of competence and was convinced to buy this luxury animal.
