Melissa McCarthy from Bridesmaids was on Conan and revealed that her character in the movie was based on Food Network star Guy Fieri. Not as much as she would've liked, though: "I tried for a long time for them to let me wear short, white, spiky hair and they were like 'You can't actually be Guy Fieri.'" So what did McCarthy do? Threw in a little Midwestern lady to temper the Fieri-ness, obviously. Here's the whole interview, but the Fieri discussion starts at about 4:15.
