I learned today that I am going to be in a commercial in about 3 hours.
Yup, totally normal.
Fun! What for? I think I was in a commercial once. It was one of those segments where they film New Yorkers from all around town singing bits of "New York, New York" and then edit them together. They came into the ice cream shop where I worked during college and filmed the owner and me singing together. I don't know if we got in the final cut..
I was in a documentary, though.
