Question: My friends and I recently had an argument over which Daniel twin was on That '80s Show. I think it was Cynthia, but my buddy thinks it was Brittany, whom he saw in Joe Dirt. Who is correct? Also, was one of them in that commercial where the guy drives through the car wash with all the shaving stuff inside?

Answer: Score one for your bud. That's Sweet Valley High, Swan's Crossing and Dawson's Creek alum Brittany Daniel, who was one of the stars of the Fox series, from That '70s Show producers Carsey-Werner-Mandabach. She played equal-opportunity ex-girlfriend Sophia on '80s. For the record, you may also have caught her as Eric's cute cousin on '70s or working with her sister and Leonardo DiCaprio in 1995's The Basketball Diaries.

On an edgier note, a Fox spokesperson told me that was twin sister Cynthia who appeared in the shaving-gel ad you mentioned. So your final score is one wrong and one sort of right I'll be charitable and call it a wash.
