I dare you all to beat this one.
So my best friend and me convinced this girl tonight that I donated part of my liver to him when I was 2 years old. The reason behind the donation was that he had incurable Jaundice, even told her that I had Jaundice but I made it through quickly so I had a strong liver. She even mentioned the fact that we each had a beer in our hand. I told her that since I was so young, my liver grew back the part that was missing and made it stronger than before.
The kicker to the story is that she's a 3rd year nursing student.
