Here's a look at tonight's sci-fi TV:
Chuck, 'Chuck Versus the Beard' – Things start to fall apart for Chuck when his flashing abilities go kaput and the team ditches him to work on a dangerous mission. Sounds like our boy could use a little lovin' from Kristin Kreuk's Hannah -- too bad he dumped her last week! Diedrich Bader and Reno 911's Cedric Yarbrough guest star on tonight's ep, directed by star Zachary Levi and featuring the return of Jeffster! (8 p.m. ET on NBC)
