Funny things you've seen your horses do?

My horse chigger rolls after i get done riding him, EVERY TIME. one time i hadnt even gotten the saddle of yet and he started rolling, He trys to eat anything thats orange, (hes addicted to carrots). He doesnt like apples or sugar cubes or horse treats you buy, he only likes carrots and corn husks. Every time you give him grain he gets a big bite then lifts his head up to say hi and drops his grain all over you.(: hes a funny horse and i love him(:
