His appearances are brief and last for perhaps one second, and features a short phrase that is yelled very quickly. In "420", Williams is so high on marijuana he calmly reports the weather. In "Lois Kills Stewie" he helps co-worker Tom Tuckerrecap the events of "Stewie Kills Lois".
He punches Peter Griffin in "Peter-assment". Peter had decided to become paparazzo, using local celebrities as his subjects. Not only did Williams punch Griffin, but he broke his video camera and glasses. To date, this is his longest on-screen appearance.
Ollie was referred to in "And Then There Were Fewer" by Tom Tucker who states he misses him.
He is revealed to be an alcoholic, as a member of Alcoholics Anonymous in "Friends of Peter G". He was once able to talk in complete sentences, but due to drinking, can only talk in short staccato ever since. It is also mentioned that he doesn't like Cher.
Ali Williams is his great-great-great-great-grandfather, and he too was a news reporter.
- Ollie Williams made his debut in Brian Griffin's Adventures Chronicles.
