Say it quietly, but the Russians might not be playing fair when it comes to athletics. There have been a few quiet hints placed about it here and there. Things like a massively successful movie about it, and the banning of Russian athletes from major sporting competitions. These are all tell-tale signs that let you know something isn't right.
If all of that was too subtle for you, though, perhaps this drawing will help. We can probably safely assume that this is a urine test at an athletics event. This athlete is so strong than they can actually destroy a bathroom via the power of urine alone. Remind us never to enter an arm wrestle with him. Especially if he hasn't washed his hands first. Thank goodness it's only urine they want a sample of, and not anything else.
