Are you sure that your real nickname isn't Cast Iron? I mean I've heard of stomachs being called by that name before, but a "steel stomach" - uhhhh - not!
And, just for the record, who are the lovely damsels holding up your arms in that picture? Your two daughters? Your wife and g irlfriend? Two random women that just happened to agree to take that shot for 10 bucks apiece? Two other guys' wives or daughters or simply two very compliant and understanding women that took pity on your azz and agreed to help make you look good... very good, in fact?
