Weird Science - Season 3 Episode 17 The Legend of Red Brick Wallace

Gary is dumbstruck when he finds out that his relatives weren't all cowards and losers. He has an ancestor named Red Brick Wallace, a gunslinger from the old west. Lisa zaps them back to the old west in order to meet Red Brick Wallace. Unfortunately, he turns out to be nothing more than a spittoon polisher. The guys are now on a mission to save Red Brick Wallace from getting shot by the sheriff, who looks strangely like Chett.
