I did something similar to that, back when I was in my 20's. I was in the hospital with a bad bladder infection. I had to give a urine sample every two hours. Several of my buddies came by to see me and I asked one of them to go to the grocery store and buy me a can of un-refrigerated apple juice. I filled the sample cup with the apple juice and when the young newbie nurse came in to collect the sample, she held it up and said it was a bit cloudy. I took it from her hand removed the top and said "Well then lets pass it through one more time" and drank the apple juice. The look on her face and the whimpering noises she made as she ran out of the room was priceless. My buddies were laying all over the floor laughing...until the newbie nurse came back in with a very seasoned RN who was packing a needle that looked like it was for use on an elephant and proceeded to tell me that if I was that stopped up she could stick the needle down the tube of my member and extract a clean sample of urine for testing. You could have heard a pin drop in that room and I went into the restroom and provided a sample quicker than I had ever done before. This was because that RN with her needle scared the piss out of me....literally!!!Take a clean child’s potty, put some apple juice in it, then dip some bread in it eating it while walking through the mall.
