Well, Jim is really the only one who is actually somewhat nice to Michael--to his face anyway. Like, when he had the party even though he didn't want Michael there, he gave in and tried to make him feel comfortable. That's kind of why I think he told him.
Yeah, I guess it wasn't the funniest episode ever. I tend to laugh, though, when others might not think it's funny. I laugh at the awkwardness and at how horrible Michael is at being a human. He was telling one of the staff not to give out spoilers for the Titanic movie! Um, let's see... I wonder how that one ends.
Oh, and I think I am still on a laugh-high from watching The 40-Year-Old Virgin last weekend. I love Steve Carell.
