This season of LIE TO ME has been fantastic – easily one of my favorite shows to watch during the week.  Tonight is the fall finale (don’t worry, it’ll be back sometime this spring for the back half), and it looks like a doozy!  Cal deals with a disgruntled farmer trying to attack DC and the lovely Felicia Day guest stars as a teacher whose class is stuck at the Lightman Group.  This preview clip features Felicia and the adorable Brendan Hines entertaining the class!
