I know the model Carrie has done work for both SlapstickStuff and Anglefan, and I'm pretty sure the excerpt I'm thinking of is from Anglefan . . . I remember at one point on YouTube there was a clip of Carrie and another woman. Carrie is wearing a dark blue top and her scene partner says something like, "All you have to do is sit there and look pretty" and Carrie says, "OK" before getting pied.
I haven't been able to source of this one, and I'm curious if anyone else has any memory of what I'm describing. It may have been part of a compilation.
