If you're at a grocery store and see a teenager with two gallons of milk . . . get suspicious.  The newest dumb stunt on YouTube is called "gallon smashing" . . . where you pretend to dramatically slip and fall WHILE carrying two gallons of milk.

--A couple of idiots did it in a bunch of grocery stores and posted a montage on YouTube, which now has over two million hits.

The question is, what would you do if you saw this in the store... and especially what would you do if you found out your precious little snowflake of a kid was doing this?
