Alliance Officer: "Seems odd you'd name your ship after a battle you were on the wrong side of."
Mal: "May have been the losing side. Still not convinced it was the wrong one."
-- Bushwhacked


Inara: "Attack." (Mal lunges at her with sword; she sidesteps and swats him on the butt; he grunts in pain) "How did I avoid that?"
Mal: "By being fast like a freak?"
-- Shindig


Mal: "Ah, the pitter patter of tiny feet in huge combat boots."
-- War Stories


Mal: (to Inara) "This distress call wouldn't be taking place in someone's pants, would it?"
-- Heart of Gold
