Season 3 Episode 2 – first aired on Nov. 26, 2000
Bender and Fry volunteer for military duty to enjoy the benefits of the soldiers' discount. When war breaks out later that same day, Leela too decides to join the all-male ranks, under the guise of Lee Lemon, and creates quite a stir for her leader, Zapp Brannigan.
Soldier: This is the worst part. The calm before the battle.
Fry: And then the battle's not so bad?
Soldier: Oh right. I forgot about the battle.
This is the worst kind of discrimination: the kind against me!
