I have a friend who did an open water swim this morning. I didn't.
She touched some mystery object with her hand and proceded to swim the next 25 yards at olympic record pace. It's something I know I've done when something touches me in the water.
I was looking for funny things to tease her about that online and I found this. Not related to open water or touching mystery things but simply pretty funny.
