That was a good episode
There are so many times when these things happen in the Sopranos. Someone will do something that's part of the story, it will seem so played and serious, but the way it's presented, you laugh to yourself. The situation with Chris and Adriana's dog was a prime example.
One of my favorites is when Tony finds out the guy is sleeping with his old Russian girlfriend and he ends up getting upset and beating the shit out of the guy with a belt. The guy was half naked. That was pretty funny and a good example of Tony's bipolarism.
