On last Sunday’s episode of The Simpsons, blue-boffainted mom Marge shocked fans when she planted a lingering lesbian kiss on pal Lindsay Neagle as hubby Homer watched.

Not to worry; the same-sex smooch was just a figment of Homer’s imagination.

But the episode, titled “How The Test Was Won,” is just latest attempt for the long-running animated series to broach the subject of lesbianism. In 2005 that Marge’s older sister Patty was outed as a closet lesbian, who consequently gets engaged to a female golf player Veronica.

Girls kissing girls is quickly becoming a big Sunday night event.

Desperate Housewives will feature a girl on girl lip lock between series stars Eva Longoria Parker and Teri Hatcher on an upcoming episode of the Emmy-winning dramedy.
