S3E17 The Legend of Red Brick Wallace

Gary is shocked to discover that his family history isn’t filled with cowards and failures after all. He learns about an ancestor named Red Brick Wallace, a gunslinger from the Wild West. To meet him, Lisa transports them back in time. However, they quickly realize that Red Brick is just a spittoon polisher, not the legendary figure they expected. Now, the group must race against time to save Red Brick from being shot by a sheriff who bears an uncanny resemblance to Chett.
