FTP Ring: Worst Fold Ever

So, Mr. Redbone's hand was good enough to call of almost all of his chips on the turn, but apparently not worth his last $1.50 on the river. How many times does he need the best hand to make the call worth it? Once in 14. He claimed later he had A5, makes the whole thing even more interesting...
