Happy ‘Back In The Day’ Birthday To David Lee Roth/Mario Lopez

Diamond Dave and A.C. Slater share a birthday today!

The one and only David Lee Roth celebrates his 59th birthday, so let's watch some old school Van Halen videos and remember when he was a rock n' roll GOD!

These are my top 5 Dave videos!

You know him now as the host of the X-Factor, but old school kids will always think of him as A.C. Slater! Nemesis of Zach and admirer of Jessie. Mario Lopez hits the big 4-0 today.
