What can I say about Jane Espenson? She was one of my favorite writers for Buffy and Angel and did well with Tru Calling as well. She wrote one of my favorite episodes of Buffy and wrote some humerous episodes of Angel. Her work on Buffy was amazing. Band Candy and Earshot from season 3 were 2 of my favorite episodes of the show and that season.
And she wrote Guise will be guise from Angel's second season and that was also one of my favorite episodes. She has written some of the funniest episodes of some of my favorite shows.
