Eric Forman's grandmother dies. I'm so glad they decided to kill that annoying old hag. She might have brought some funny moment, but without a doubt, she was the most annoying character on the show. I found the parts funny on how they made fun of her death, it was hilarious.
The five stages of grief. Yes, they have been going through it as well. I enjoyed seeing how they copped with the whole situation. Very nice. We also get to see a different side of Eric, which was quite OK, but he was really out of character in this episode.
Overall, excellent episode.
