I think Johnny the Greek is the guy who Melissa WANTED to marry who kinda blew her off. Rich Italian mobster. Rumor is, he toyed with her emotions and strung her along. Then along came Joe Gorga and she married him because Tommy the Greek wouldnt step up and marry Mel.
Something like that anyway.
ETA: what thatblonde is saying is to not believe that "Tommy the Greek" is the son of Melissa's former stripper boss, that the stripper boss's son would be too young. Stripper boss's son must be named Tommy too. Different Tommy.
