👔 Classic Dad Joke

Why do ghosts make bad liars?

Because you can see right through them!

Why This Joke Works

"See right through them" is an idiom for recognizing someone's deception — and ghosts are literally transparent, so you can physically see through them. The metaphor and the physical reality of a ghost's body line up perfectly. It works as social commentary and supernatural biology simultaneously.
