Best Anteaters

Alright, listen up, buttercup. This joke is playing on the words "anteaters" and "aunt eaters." "Anteaters" are animals that eat ants. But the joke wants you to think about "aunt eaters" which sounds like "anteaters" but is about uncles eating aunts. So, the joke is saying uncles make the best "aunt eaters". You probably have some aunties yourself, huh? You look like you have a lot of family, but they probably don't like you.
