In an attempt to pass a drug test after recently ingesting an illegal substance, one uses a catheter to remove all of the urine from the bladder. Once removed, it is replaced by the urine of someone who would piss clean, also by catheter. The result is a clean urinalysis test for drug users everywhere.
