To think that back then people on the street laughed and possibly ridiculed this young, semi-nude Arnold with his penis edging out of his trunks. Little could any of them (Arnold included) have known that years later this same foolish youngster would end up dominating professional bodybuilding, Hollywood & politics.
By far, the most impressive bodybuilder to have ever graced the earth.
EDIT: Just took a look at the link Pellius posted and noticed 2 distinct things worthy of mention.
(1) How annoying would it have been if you're out there doing construction work (man shit) and this apparent flamboyant homosexual decided to stop, smile and pose in nothing but a thong? To no surprise, the guy (who looks a lot like Ralf Moeller) carrying the steal beam looks perturbed. This is evidence that Arnold was a master troll.

(2) Does anyone else think that his package looks more like camel toe vs an actual huge hog in the picture below?

That is all..
