Anya AND Tara! Eeee!

Either "Spock's Brain" or "Turnabout Intruder".  And don't be so stiff regarding the space hippies, Herbert!

James was my least-favorite character on "Twin Peaks".  "Oh crap, he's singing!  Where's the MUTE button?!?"  And that story line was weaker than wish tea (e.g. you have a cup of hot water and wish you had a tea bag to dip in it).
