Go to a pet shop and buy a fancy looking pet collar and leash. Then, the next time you see a dead animal in the road, attach the leash and collar setup to its neck. Attach the whole thing to revengees rear bumper, making sure to toss dead animal under the car so it won't be seen. When revengee drives away, chances are he/she will be stopped by either a cop or a member of some animal lovers group for draggin some poor defenseless pet down the road. Either way, they are gonna have some awful quick explaining to do!
