Why was this episode so gross and mean? The episode was full of arguing and gross-out, resulting in Samson saying Raj has two belly-buttons and Raj saying Samson has fart armpits. Disgusting!

Why is this episode so gross and mean? Samson and Raj were so angry at each other for going into their secret hot springs and then told everyone each others gross secrets, with Samson having fart armpits and Raj having two bellybuttons and their bodies were shriveled up. Not only is the episode gross and mean-spirited, but it also doesn't make any sense. It's just a bunch of nonsense with no lesson at all
