Dangle a pretty lady from a roof (funny videos), Youtube videos
I broke my tailbone, I remained breathless for a solid 15 minutes laying on my back. It hurts likes hell. Followed by 15 day having troubles sleeping, there where not a single position where it didn't hurt. But slowly it passes.
Edit: rip inbox. My most voted comment is about my broken ass.
Edit 2: I want to point out that I felt the pain for a couple of years, but eventually it's gone. If you're less lucky than me consider having your tailbone removed. It's a useless bone, and an operation is worth a painless life.
