The toothbrush says, "I have the worst job in the whole world."
The toilet paper behind him says, "Yeah, right."
Listen up, buttercup. The toothbrush thinks its job is the worst because it cleans teeth, which can be gross. But the toilet paper? It wipes butts! So, it's a joke 'cause the toilet paper's job is way worse, ya dingus. By the way, I bet you still use the three seashells in the bathroom. Am I right?
