No not "always make sure it's covered"....I don't wanna know about that kinda stuff.
I mean more the stuff that your rents used to tell you when you were young that turned out to be a crock of crap....
For example....
"Good guys always win" (Danny D wouldn't be boss if this was true)
A nice one I heard the other day was that a guy used to be told by his Mom and Dad that the music on the ice cream van when it got near the house was a warning that he'd already run out of ice cream!!
