The lesson of Julia Louis-Dreyfus is: Don't be fooled by a frumpy presentation. During the raven-haired, cheeky stunner's eight-year run on the massive comedy hit Seinfeld, Julia's cleavage displays were so few that she might have counted them on the nips of her own two tits—although she unwittingly unveiled half that equation when her Hershey-Kiss-like left-side milk spigot slipped into view when she bent down on the 1991 episode "The Busboy." During early stints on laugh-arousing institution Saturday Night Live and as a regular on Day by Day, unsuspectingly juggy Julia managed to charm and beguile but never as a knockout bosom flaunter. Then came Louis-Dreyfus's surprise appearance at the Emmy show, squeezed lusciously into a dress slit almost to the navel, with boobs dripping out like the thinking man's J. Lo. Now her mammaries are never far from mind. Consider that when checking out Julia's comeback TV series, The New Adventures of Old Christine.
