One of my friends showed me this (well, her version) a while ago. The idea is that you put forward four things, three of which are true, and one of which isn't true, and see if people know you well enough to know which is which.
So, here goes. Can you guess which is false?
I rode on the top of a train down the side of a large mountain range, through tunnels and all.
In college, I worked in a lab and did histology on rat brains.
I swam with wild penguins in the wild, close enough that I could reach out and touch one; it felt rubbery.
I officiated at a wedding ceremony.
Feel free to play yourself.
