because you will have to take multiple, back-to-back diarrhea trips to the bathroom all night long while you're trying to study for your Chemical Engineering exam.

Don't pee in the pool after you've taken Azo

because your body will produce a bright orange cloud of urine that will be extremely noticeable to anyone who is swimming in the pool with you.
