Short plot description from NBC’s site: Ryan invites Michael to be a guest speaker at his business school. Meanwhile, Dwight battles a bat that gets loose in the office while Pam (Jenna Fischer) invites co-workers to her first art show. In her nigh-indispensable blog, Office star Jenna Fischer writes, "I loved having Joss around on set. He is a huge fan of the show and knew every little detail and nuance about our characters. As a result, he was very focused on how to direct us to get the very best performances. I remember one day I was doing background work for a couple of hours and out the blue he came up to me and said, ‘Jenna, I love the reaction you are doing back here. It’s perfectly Pam!’ He was watching our background performances…so awesome." Jenna insists it’s pure coincidence that the episode happens to feature a bat – which the cast named Gary and which she describes as "super-cute." That’s so perfectly Pam!
