I thought that was a sand nagger
You're on morphine, you're driving, you see a car, you think it's a sand nag, you get mad enough to punch a wall, then you realize it's not a sand nag and you're the happiest person in the whole state.
I saw a car, thought it was a sand nag, I got so mad I almost hit a tree.
Morphine made me think that car was a sand nag, I got so angry I wanted to punch the sky.
That car was not a sand nag, but I almost cried from rage.
