Or, at least, on the Buffyverse.
Charisma Carpenter became a worldwide wet dream girl when playing Cordelia Chase, first on Buffy, The Vampire Slayer (1997-1999) and then on Angel (1999-2004). Despite starting out as the vacuous "bimbo" in the first season of Buffy, she quickly won the love of viewers everywhere, smitten by her charisma (pun, obviously intended) and her ample charms... some of which became very prominent whenever she donned a tight shirt. Indeed, as the Playboy photo shoot she did for the June 2004 issue well attested, those wonderfuly round breasts are natural fuel for male fantasies everywhere.
Well, it was on Vincent Kartheiser, who plays Angel's son Connor, that fell the burden of groping Ms. Carpenter's right breast in the episode Slouching Toward Bethlehem (episode 4 of season 4, 2002). The episode marks the return of Cordelia from the "higher plane" where she has been herself slouching for the previous three episodes of the season. Returning with a bout of amnesia, Cordelia takes refuge with Connor, who doesn't waste any time replaying the most complex Oedipus on modern TV. Sensing the presence of intruders from the evil law firm of Wolfram & Heart, and pretending to be warning her not to scream, he takes the chance of palming Cordelia's breast, in a what-the-fuck-were-they-thinking heart-stopping moment.
