Profit and Lace
Bender asks Fry to help him... er... her find a pantsuit to wear on Late Night, but instead appears on the show wearing a skirt.
I guess they couldn't find a pantsuit.
Also, Bender had been a gender bender before, when that became his gimmick in Ultimate Robot Fighting.
It's a womans perogative to chage her mind! Especially if it involves clothes.
