John P. Navin, Jr.

John P. Navin Jr. (born July 24, 1968) is an American film and television actor from Philadelphia. He is well known for his roles in the 1981 drama film Taps and the 1983 movie Losin' It, both of which co-starred Tom Cruise. He also starred in National Lampoon's Vacation as Cousin Dale. Navin also appeared in the pilot episode of the TV series Cheers, which starred his Losin' It costar Shelley Long. He appeared as the first (on screen) patron of the bar, and delivered the series' first line, inauspiciously presenting Sam Malone with a fake I.D. and claiming he was a Vietnam veteran.

Navin has since left acting.
