Ovipositor
The cave crickets that live in my crawl space and jump onto my head each time I enter or exit have this giant pointy thing on their tail end that looks like a stinger.  It frightens me, to say the least.  After some research, it turns out it's called an ovipositor, which is a body part certain insects use to place their eggs in the ground.  On crickets, it's a non-violent appendage.  On other insects, like bees and wasps, it's a stinger. #nature

Bad part of town
I was driving around a small city recently, and I realized I crossed the tracks into the bad part of town when I saw the following businesses:  Cash for gold, payday loans, and bail bonds.  I wonder which came first, the bad part of town, or the businesses in the bad part of town.
