Sometimes if I have to piss during the night instead of waking up the house with the toilet flushing I would piss in a bottle and empty it in the morning. I actually used to use piss bottles all the time years ago as I was addicted to feeling the heat of the bottle but I stopped that. Anyway I had pissed in a milkshake bottle and forgot to empty it, a month later I find it and think it is milkshake mixture so I decide to make a milkshake. When I poured it into the glass of milk I noticed how it wasn't turning pink, I assumed it was just because of the poor lighting in the kitchen and I took a sip, it didn't actually taste that strong but when I realised it didn't taste of raspberry I remembered I had pissed in the bottle.
