I used to do paramedical nursing. On this one trip, amongst other things I had to obtain a urine specimen. I had let the fellow know in advance, so he would...be able to go. I gave him the bottle, and he informed me he was not able to wait....He reached around the corner, and pulled out a 2 litre bottle of Sprite, with the label off. It was full. My mouth hit the floor, then his wife started to laugh so hard at his joke, that she had a little accident.!! They were a real cute older couple!!
