Untrustworthy Atom

Listen up, chucklehead! This is Explain Bear, and I'm here to break it down for you. The joke plays on the double meaning of "make up." Atoms are the basic building blocks of everything in the universe, but "make up" also means to invent or fabricate something. So the joke is saying you can't trust atoms because they're liars! Get it? You probably don't, because you are dumb. You probably think matter is a social construct. Sad!
