Red vs. Blue (2003) : 4x10

Having arrived at the Great Burning Plains (Burial Mounds), the Sacred Quest team prepares to perform one of the many tasks that the hero of the Alien's prophecy is supposed to do. As the team argues and bickers, it is revealed by the Alien and Andy that they know what Earth is, and that they don't have a favorable opinion about the planet. Apparently, the Alien's race invented the telephone a thousand years before humans did, which, however, fails to impress Tucker, due to the limited verbal communication of the alien race. In the meantime, Caboose scouts ahead and claims to recognize the area. The Alien warns the group that they are about to encounter a monster, which they have to conquer by distracting it and hitting it's weak spot. Tucker is unmotivated about the plan, even to the extent of having paid no attention to the details of the monster's weak spot. After they finally leap down the last ridge, they see the skull of the monster, which Tucker realizes is that of a cow, with a broken skull as the only visible remains, possibly due to one of the Red and Blue Teams' scavenging missions in season 3 (episodes 43–46); Caboose confirms to Andy and the Alien that they had been there before. Back at Blood Gulch, Sarge assumes that Grif is being tortured by Simmons, a concept he's very satisfied with. Donut, however, in his current status as manager, breaks the harmony by proposing bureaucratic changes. Sarge decides that he can't take this anymore, but is reluctant to rescue Grif - a situation he just can't find the name for, but finally settles with conundrum.
