if this did happen (which it probably did not) they probably saw a pile of towels used to remove PROTAN (which comes off brown)
stupid rumor, he was big..............but not so big he couldnt reach his asshole., he had long arms...........
those morbidly obese people who suffer from this cant reach cause their guy and ass and arms get so fat...............but bodybuilders dont have that problem cause their waists and asses stay relatively small
he didnt even have that big of a back, it was one of his weaker parts
who knows how rumors like this start,,,,,,bodybuilders are worse then old jewish housevives with their gossip
what PROBABLY happened is Greg was using a bunch of white hotel towels to remove PROTAN after a competition or posing or somethign..........and someone in his room caught a glimpse of all the dirty brown/bronze towels as they passed thie bathroom and thought is was actually shit on the towels
either that or there is no basis for this at all and it just somethign some jackass on the internet made up (which happens constantly on these kind of message boards)
