File:Watch out Sheldon! Boulder! Boulder! OUCH!!!

Description
In this Mack and Moxy episode, "A Friend Who Reads is a Friend Indeed", Shellfish Sheldon as usual tries to get to the Helpees before anyone else to keep them just for himself. He thinks he's smarter and gets on the bark of a tree to slide as fast as he can down the hill but he doesn't realize that there is a boulder in the way and he's in for a painful crash. Perhaps this will teach him a lesson and he will understand that being selfish never leads to anything good!
