Point being that his inability even to present a coherent story, keep track of his lies from day to day, or even comprehend the subject matter enough to not make a fool of himself, belies the notion of a mind sharp enough to even keep a simple count on a deck of cards.
Add to that the emotional instability, constant whining, inability to keep his mouth shut, epic indecisiveness and obsession with what others think of him - how could this type of personality be a success at anything, let alone in assuming a role where staying cool and collected is what it takes?
Has this mental deficient demonstrated one character quality or point of keenness that would be in keeping with the card shark he is so desperate to portray?
He also has a ridiculous deficiency when it comes to reading the room - still doesn't get that no one believes him and has resigned him to the scrap pile for some time now. Inability to read the room also translates into someone who could never survive in a casino environment, certainly not under the radar as he claims to have been cruising.
Seriously, I can't think of one subject on which he piled on that he hasn't ended up making a fool of himself over other than blackjack play in general where he has almost never described a single hand of actual play, and always speaks volumes in theory on what he read or heard from others.
There's no substance here, just a damned fool who keeps making a bigger and bigger fool of himself the more he opens his wide, loose mouth.
And worst of all, he doesn't even realize or accept how painfully obvious it is to everyone that he's a complete fraud. The complete opposite of any Delphic maxims, that's for sure.
