My nick comes from the days when boys would be boys (and also be the town terrors).
To make a long story short...A friend had an old Caddy thsat we would would tear around town in on summer nights and week-ends.
The old Cadilac coupe de'ville was a hand me down ride from his grandfather...white with matching interior, white wall tires and and a decent stereo to boot!
On the dashboard was superglued a "religous bobble headed figurine"...aptly named by me and my co-horts "jehovah"...you know...those people you want to punch in the face when they keep knocking on your door at 7:00 am in the morning wanting to convert your sorry arse.
Anywho...we would smack that bobble headed thing when we wanted  an easy and cheap laugh...trying to finally knock it off of its obviously impermeable base...to no avail.
hence the name >>>dashboard_jehovah
Have had a few inquiries as to why I chose this nick...hope this clears up the confusion for anyone interested!...peace, Mark.
