what people need to realize is that tom is a bodybuilder and his muscles are huge so of course he's going to beat marcus in an arm wrestle -- marcus is probably a pretty strong fella but look at tom, his guns are BIG
anyway -- im not sure if you watched BBLB earlier but marcus and tom had a few arm wrestling matches as a joke -- and im sorry to say that marcus lost -- tom was just too strong
still though, tom walked out of the house after only a few days, complaining of being "bored" (
) so if it's mental strength you're looking at, all the other housemates beat him -- but physically he's probably stronger than all the other housemates combined
