There is a TV ad currently running, where a guy goes to an open box of tablets – remember that – on the kitchen worktop, pops one out of the blister pack, takes it and immediately pukes up a dead rat. Then goes to the sink and pukes some more
Why? Because his meds were laced with rat poison, which is what happens when you buy drugs on the evil Internet. And taking rat poison causes you to puke dead rats, of course.
