Worst injury ever.
When you weld two closed end sections of pipe together with a full seam weld you need to drill a small hole in a section or the air pressure built inside will cause the molten fucking metal to shoot at you when you finish the weld. Someone was supposed to do this before they gave me these pieces to weld today. Needless to say they didn't. So I got hot metal spatter propelled at my crotch today burning both dick AND balls.
