The most gigantic beneath-the-belt bulge in history.
George accidentally gets a busboy named Antonio fired, and goes to his apartment to apologize. Antonio is angry, taciturn -- and a Greek god. Viewers wanted to know, who is this Michelangelo's David come to life? This Apollo masquerading as a mortal? And why did the producers squeeze him into jeans so tight that his superheroic endowment was so completely and obviously visible?
Not that there's anything wrong with that.
He was 29-year old David Labiosa, who had been appearing on tv and in movies for a decade. His credits included The White Shadow, Hill Street Blues, T. J. Hooker, and the movies Private Sessions, A Sinful Life, and Uncaged.
He had never had such a revealing role before. Or such a gender-transgressive role. Hispanic actors generally are cast as super-macho gang members, thugs, and streetwise detectives, but Labiosa's Antonio resists gender expectations by having a pet cat named Pequita, and by effusively hugging George at the end of the episode.
Maybe that was the point: the stereotyped super-macho Hispanic guy turns out to be sensitive and sweet, i.e., gay.
Hopefully he won't be remembered solely for the gigantic bulge on Seinfeld.
