|Episode 0668|| Back and Front|
Marshal Grover asks Fred why he's walking backwards -- he can only see where he's been, and not where he's going. He also wants to know what happened to Fred's head. Fred explains that Marshal Grover doesn't know the difference between front and back. "That is a terrible, mean, cruel thing to say to me, Fred!" Marshal Grover exclaims. "It is true, but..." Fred tells Grover that he's facing backward, and if he turns around, he'll see Fred's head. Grover turns around, and cries: "Oh, Fred! I've missed you! Oh, it's good to see you!" Fred says that if he stays turned around, he'll be able to see where he's going. Grover tries it, and he's proud to know the difference between front and back. Unfortunately, now his head is resting on the saddle, with his feet in the air.

Grover orders a glass of milk, and the bartender asks if he wants the big glass, the bigger glass or the biggest glass. Fred tells the bartender that Marshal Grover doesn't know the difference, so the bartender shows off all three sizes. Marshal Grover and Fred come behind the bar to get a closer look, breaking bottles and glassware. The annoyed bartender shouts at Grover to choose a glass, and Grover picks the biggest glass. The bartender asks if Fred wants anything, but Fred says, "No thanks, I'm drivin'." As Grover rides his horse out of the café, the bartender asks who's going to pay for all this stuff. Grover says he'll be back to pay for it tomorrow. Panicked, the bartender says not to come back; it's on the house!
