That's not the story Boob tells of himself as a young adult. He speaks of working multiple jobs to make ends meet (remember stocking shelves at the grocery store and the pantry at the TTH). They lived in a tiny house on his car lot, and if memory serves it was there that Meech had her infamous laundry room breakdown.
All this to sat that he wants everyone to believe he came from nothing, pulled himself up by the bootstraps, etc. I do question their real estate business. If it was doing so well, why was Mary managing a yogurt shop? She had a RE license.
So many holes in their story...
