I loved the way Richard and Galavant were teamed up this season, and became best buddies. As others have said, Richard was the standout for me, so much so that I started watching Psych on Netflix! Timothy O. is an amazing actor with quite a range of talents.
Everyone else has already mentioned the best parts of these last two episodes, but I'll add one more. I don't have access to the original quote, but it was something like, "When you presume, you make a pres out of you and me." Pres? Hee hee! It makes me think of one of House's funny lines, "When you assume, you make an ass out of you TO me."
I have managed to bring in a few more viewers to the show this season, but unfortunately, they don't have Nielsen boxes. If anyone has a plan to try and keep this around, count me in! Everyone I know who watches it, loves it as much as we all do here.
