30-50 feral hogs

Referencing a post on Twitter in which someone asks "Legit question for rural Americans- How do I kill the 30-50 feral hogs that run into my yard within 3-5 minutes while my small kids play?". In the original post, it was supposed to be defending gun laws. Now it is used as an expression when something says something improbable.

Person A: What if improbable thing happens??
Person B: What if there were 30-50 feral hogs?
