(S01E18) Joel Mchale caught a McPheever this week when Katharine McPhee guest-starred as Amber, a hot chick on campus. The format of 'Community' makes it so easy to drop in guest stars, and yet they didn't just make McPhee simply another student. Instead, we got a "Family Day" event where everybody got to bring in members of their family.

On 'American Idol,' where she came in second to Taylor Hicks, McPhee always touted herself as a singer-actress, so I was looking forward to seeing what skills she would bring to the set. While she wasn't given a very challenging role in Amber, she proved that she could hang with the big boys without sticking out like a sore thumb, so I'll give her kudos for that.

It was a blast seeing Shirley's kids again, as well as Abed's dad. Troy's grandmother, on the other hand ... I don't even know what to say. That mean old relative is a sitcom staple, but still this on went in a very disturbing direction. "I don't understand you, Britta!" Troy shouted to her at one point, and I'm right there with him.
