Are actors smart?

[Rexmons]

one of the best trainwreck interviews i've ever seen was conan o'brian interviewing jeniffer garner, she starts telling a story about how she got accidently punched in the lip during a fight scene and her lip swelled up to the point she "looked like one of those african ladies". then later in the interview conan uses the word "snuck" and she very patronizingly reprimands him by saying "snuck" is not a word and because he graduated "Harvard", should know better. of course when they came back from commercial conan was sitting there with a dictionary pointing to the word snuck.
