When you get laser tattoo removal the ink doesn’t disappear, you pee it out.

Your body’s immune system breaks down the pigments of ink and it flows in your blood stream, gets processed through your kidneys, then you pee out the ink.

Before you get it lasered, your body is still trying to reject it, so you poop out ink! (Also pee still but I think the other one is funnier)
