Bob has had a number of small roles in movies, and in commercials also.
One good commerical can net you $30,000, with residuals...
So if there is an oppurtinity, why not, for anyone.
As for Bob, working with bb.com, and Weider, and the emcee of the Olympia means that Bob is having a great year, plus radio show, plus Del Taco commericial, plus getting married, new baby... damn.... he can afford lots of special shiny shirts...
