After Dan Blankenship admitted on the show that there was no treasure on oak island a few seasons ago, Dave had a hard time attempting to keep a straight face in scenes where they attempt to showcase something as legitimate.
He saw the writing on the wall that the current hoax scheme was winding down and getting harder to continue the weekly script of teaser bobby dazzler finds, out house holes being called “entrance to tunnels”, and yet even more ridiculous fictional theories.
He took the money and jumped ship (not the fictional ship in the swamp).......
Probably didn’t want to be involved in the upcoming oak island theme park in the plans...
