We've all done this. You're drivin' down a Maine country road an you see a sign that says "Frost Heave". The problem is, the big friggin' bump that the sign is there to alert you to, rocks your undercarriage just seconds after you read the caution.

Watch as he hilariously explains what happened which begs the question, "Do those warning signs really matter at all?"
