Ralph Deep End of the Sandbox T-Shirt Ralph's not allowed to go into the deep end of the sandbox, he may never come back out! You have to love all the things that come out of Ralph Wiggum's mouth, and with true Simpson humor, Ralph keeps them coming! Whether Ralph is saying things that just don't make sense or eating things he shouldn't Ralph just keeps us laughing and laughing. This brown t-shirt is decorated with the image of Ralph Wiggum with the saying "I'm not allowed to go into the deep end of the Sandbox". Another great Simpsons' quote!
