Percy Kilbride appearance!

I read where Percy Kilbride (who is best known as Pa Kettle in the Kettle movie series) has a very brief appearance in this movie. It has been many years since I have seen this movie and don't remember seeing him and he isn't listed even as one of the uncredited cast members. Does anyone know where he appeared in this movie? I plan to watch it again when it is shown on tv to watch out for him.
