This is my best one.
We where at a BBQ at our friends field, and I had an urgent shit. One of which you get goosebumps all over your body. I was speaking to a friend of mine and even he had a shit. We were contemplating what we should do with another buddy of ours and he suggested a brilliant idea.
This was his idea: We take a bricks (the one in the featured image) and we both use the bricks to shit in it at the same time, whilst resting our backs together.
With a few drinks in mind we said why not. I kid you not, it worked. One of my best all time shits that I ever had. Cracks me up every time.
