Dorf on Golf is a 1987 comedy film starring Tim Conway, Vincent Schiavelli and Michele Smith. The film is the first in a series of eight films released by Conway using the Dorf sporting theme. The film had a total cast of three.
Dorf is the main character, giving instruction in how to play golf. He is apparently Swedish (his accent is from Conway's "Mr. Tudball" character on The Carol Burnett Show) and is about as tall as a 5-year-old; his height and some humorous movements are achieved by Conway standing in a hole, with fake shoes attached above his knees. As a result, Dorf always stands in one place.
Leonard is Dorf's clueless caddy, about twice as tall as Dorf. As Dorf tells Leonard what to do, he'll usually answer "Right" (when he finds the Five-Iron, Dorf proclaims, "You get your numbers and colors down, you're going to be a real threat!")
Boom Boom is a posing character that "helps" Dorf out when he's explaining the "dog-leg" hole. She annoys Dorf when her hot dog sticks to his stick and when she drops an illustration because she's fixing her hair.
