The Joke
A child walks in on two adults in a compromising position in bed. The classic sitcom trope plays out: the child asks "What is Mommy doing to Daddy?" and the flustered parent blurts out the standard cover story -- "It's nothing, buddy, we're just wrestling!" The child, however, is not satisfied. They point out that the scene doesn't quite add up: "That explains the chair," they say, implying the presence of a folding chair (a staple weapon in professional wrestling). The parents are caught in an awkward spot where their cover story accidentally lines up with an even more bizarre reality.
The comic subverts the classic "walked in on parents" joke by having the child take the wrestling excuse literally and apply professional wrestling logic to it. The child's concern isn't about what the parents are actually doing -- it's that they appear to be engaged in hardcore wrestling complete with props like a folding chair, which in the world of WWE-style entertainment is used to hit opponents.
The Humor
The humor works on multiple levels. First, there's the timeless comedy of parents scrambling for an excuse when caught by their kids. But the real punchline is the reversal: instead of the child being naive, they turn out to be weirdly perceptive about the wrong thing. The folding chair detail elevates the absurdity -- the audience is left to wonder why there actually is a chair involved, making the parents' situation even harder to explain than the original one. The final panel shows the child cheering "Booya!" as if excited about the wrestling match, completing the professional wrestling framing.
