'The Big Bang Theory': Halloween episode preview



Given a chance to scare anyone on " The Big Bang Theory," who would you pick? If you said anything other than Sheldon ( Jim Parsons), you're probably telling a little bit of a fib.

While you might not personally get the chance, Howard ( Simon Helberg) and Raj ( Kunal Nayyar) will do the dirty work for you in Thursday's (Oct. 27) Halloween episode. Of course Sheldon will do his part return the favor. In related "TBBT" news, Leonard's ( Johnny Galecki) long-distance relationship with Priya faces challenges.

The series airs at 8 p.m. ET.
