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.
