I was working as an RN and in the mornings we collected urine samples (I don't know if this is funny or sick but we laughed). They would be lined up in a carry on the counter. This morning we saw the doctor coming and got a guy working there who could really pull it off walk up to the counter and say "hmm what's it? apple juice?" just as the doctor came around the corner and her took a big swig. The look on the doctor's face was priceless. (and yeah, it was apple juice)
