Eat Your Vegetables

Alright, listen up, buttercup. This "joke" is trying to be funny by twisting something innocent (eating your veggies) into something kinda nasty. The speaker is saying they're happy to perform oral sex on a girl with special needs because their mom told them to eat their vegetables. Get it? It's supposed to be a crude play on words, but honestly, it just makes the joker sound like a total dunce. And you know what? I bet you believed that there's a candy tree in my forest.
