You would be crazy to make any kind of bet with that balkan con man. If he had any honor (which he don't) he would have shown a video of his wife "easily" squatting 140kg and himself squatting 260kg (572lbs) for 40 reps. He know that you (or anyone else) won't put $40,000 on an internet bet.
Con man posts under his own name, gives exact address where he could be found and where he could accept the challenge - on spot...No video cameras necessary, no special effects...just TESTICULAR FORTITUDE - to show what kind of man hides behind OneManFag or many other "cyber heros" user-names...
Care to visit? Bring your daddy with you and extra set of pampers...
