Pop!

'You know how people
have these little habits
That get you down. Like Bernie.
Bernie liked to chew gum.
No, not chew. POP.
So I came home this one day
And I am really irritated, and I'm
looking for a bit of sympathy
and there's Bernie layin'
on the couch, drinkin' a beer
and chewin'. No, not chewin'.
Poppin'. So, I said to him,
I said, "you pop that
gum one more time..."
and he did.
So I took the shotgun off the wall
and I fired two warning shots...
... INTO HIS HEAD.'
