Interesting. Had no idea Pat not only had acting experience, but 10 years worth; he always seemed like he had more of a broadcasting background, as opposed to acting (like Gene Rayburn, Peter Marshall, or--yes--John Davidson). Also nice to see that he doesn't view such a thing as summerstock to be "beneath" him.
/And anyone who saw Goddess of Love knows that asking Vanna to act is not a good idea.
