Interesting timing to this thread.
Last week one of my playing partners "sharted" and soiled his pants. I was absolutely astonished when one of the other guys in my foursome pulled an extra pair of clean briefs out of his golf bag and handed them to him. He said he always carries a spare pair for emergencies.
I'm not sure which was stranger, a guy carrying extra briefs in his golf bag, or another guy wearing someone else's underwear.
This was a real eye opener...
