Best I can think of is Hoist by Their Own Petard.
Bob's best argument for whatever cause he's defending ends up being the one that causes him to lose.
Say Bob is a 20-year old campaigning for the local school to teach creationism instead of science. His best argument at the PTA meeting is that his mother and father are brown- and red-haired and he's a redhead, which shouldn't be the case according to genetics, and therefore Science Is Wrong. Cue a lot of awkward coughing among the older PTA members who remember that 20 years ago, the local mailman was a ginger...
Bob's mother confesses that Bob is indeed the mailman's son, she gets a messy divorce from Bob's dad, the school gets increased funding for its science teachers, and Bob is left humiliated by the entire ordeal, all because he submitted an argument he thought was unbeatable.
