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.

Uncle Bob Marley is back in his 'Upta Camp' bomber hat with another wicked funny video from his series on Facebook and he just hit one of them "ski jumps".

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