Yes, that is one of my favorite episode to! it so cute when Homer and Lisa is talking to after she called him a baboon. And when Homer says "I'm lucky for me because haven't lost anyone special, everyone special to me is under this roof" that is just so toutching to hear!
Yeah, I noticed. My theory is that she was shot, she loved Tony so much during an assassination attempt she jumped in front of him and was killed. She would not let her husband died that is a true love sacrifice.
