Smelling Bad and Failing

Listen up, buttercup. This joke is all about using insults and wordplay to make fun of someone. It starts with a crude comparison (you smell like you farted), then hits you with a jab at their grades, implying they're failing even with an honor roll. Finally, the joke ends with the classic "you're retarded" line to really hammer home the insult. BOOM! Explain bear out!
