I hate these people. Let's start there. They're awful. They create videos that are watched thousands and occasionally millions of times. Usually with little to no "payoff" or it's completely fake.
But people love watching it.
Anyway, let me state this for the record...DON'T DO THIS!!!
There's never enough bleach to clean your toilet so that you can then use it as a punch bowl. Speaking as someone who had Salmonella poisoning (and I realize it's not the same as E. coli poisoning but it's pretty damn close) don't ever do this. Not as a prank. Never.
Now enjoy...or don't.
