I guess I'm into water, now
One funny thing... you know those places where you drink in a paper/plastic cup? Supposedly, they are clean, right? After all, they come all packed together, one inside the next one... But as soon as people take one out and your drink is inside a bottle or a can, bam! The cup goes upside down on top of it!
"Ah! Who's clean now, you dirty little cup?"
