This sounds like a make-believe post to me. How could anyone think that behavior was funny? When you find yourself with a dog that has hurt someone else and wind up in court, will you laugh at the judge too?
You'd be wise to heed the advice of all these responses and get to some training classes. This is not a 30 pound Cocker Spaniel you're raising and if you really do love him, you'll give him what he's lacking........training and discipline.
