I worked with a guy one time that had orange urine. He had stepped out on the wife when he supposed to be at a meeting so he thought for sure he'd gotten the bug. He's taking a leak one day when the wife walks in and see's this orange stuff, the idiot tells her all then goes to the Doctor.
Turns out He had a bladder infection! We sure got a good laugh outa that one.
Could the orange color have been a bit of blood in the semen? Sometimes this happens as we bust a small vessel or something in the plumbing, usually only happens once and then things return to normal. I'd say if this happens again I'd be seeing a doc just in case!
