I’m friends with the son of the director, Errol Morris. I’m friends with his son Hamilton. I went with him after school, him and two of my friends. We didn’t think we were going to make ads; we were just going to get the free set food. So we go there, and they’re like, “We need a couple more people, so I guess the three of you can make ads.” So we all made ads, and me and Hamilton’s got picked. I had no idea I was going to do it until I got there.
Feiss' popularitet voksede til et punkt, hvor hun blev inviteret til at være med i både David Lettermans og Jay Lenos tv-programmer, hvilket hun dog takkede nej til i begge tilfælde.
