Team Fortress 2's scout class has a secondary weapon called "Bonk! Atomic Punch". A tumbler of the item went for sale on the Valve store last week, and today Reddit user Rajorface uploaded pictures of the 'warning label' on the Tumbler. As you might expect, the fine print is ridiculous.
Here's a picture so you can see for yourself, though you can find some more in the Reddit thread.
Thankfully, this thing only holds what you put in it -- it's a tumbler, after all -- so you don't have to worry about any of this being true.
