Want to ruin someone's day?
Send them a bag full of real looking piss.
Just imagine the look on their face when they reach inside the package expecting a letter but instead pull out a bag full of disgusting real looking piss. We'll make sure to spill plenty on the outside of the bag so when they take it out of the package they'll get it all over their hands.
You know they're going to absolutely lose their sh-t as they try to wipe what they think is someone’s real piss off their hands and wonder who the f-ck sent this to them.
100% anonymous. 100% hilarious.
