It's a Gift (1923) is a short silent movie comedy film featuring Snub Pollard and directed by Hugh Fay.
One of them suggests that they contact an eccentric inventor (Pollard), who has devised a new gasoline substitute.
When he gets the message from the oil company, he is excited about the opportunity to demonstrate his innovation, and jumps into his "magnet car".
The most famous sequence in the film shows Pollard using a large magnet to put his car into motion.
