Line up crackers on a waxed-lined cookie sheet. Melt the chocolate in a double boiler or microwave. To keep your hands from getting messy, put a large mixing spoon in the pan with the chocolate, get another regular spoon. Put a cracker onto the bigger spoon and using the smaller spoon pour some chocolate over it and flip the cracker do it the same way. Scrape the excess chocolate in the pan. Repeat the same method for each cracker. When all the crackers are covered with chocolate, sprinkle crushed peppermint on top of them. Then put the waxed-paper cookie sheet in the fridge until the chocolate firms up.
