Mother-in-Law Outing

Alright, listen up, buttercup. This joke is about a person who says they "took out" their mother-in-law. At first, it sounds like they went on a friendly outing. But then BAM! The punchline reveals they're a sniper, implying they "took out" their mother-in-law in the deadly sniper way, not in the having-a-nice-day way. You probably thought they went to the Olive Garden, you silly goose!
