[No.] 22A [Episode Name] Lunar Litter Bugs [Air Date] April 8, 2006 [Description] 
The garbage pipeline seems to be broken when all the garbage has been appearing on the sides of Stinky Lake instead of in the Recycler. So Jim has to dive into Stinky Lake to check out the reason. At first, Jim is hesitant because the lake is stinky and looks dangerous, but then realizes that it's beautiful down there and there's no danger.
