"Hadst thou but seen thy knights trodden under horses' hooves, thy palaces invaded and ransacked for booty, thy ladies bought and sold at four to the dinar of thine own money! Hadst thou seen any churches demolished, the crosses sawn in sunder, they garbled gospels hawked about before the sun, the tombs of thy nobles cast to the ground...then thou wouldst have said, 'Would God that I were dust!'" - Letter to a Crusader King after destroying his army and capturing his castle.  This is the precursor to "in ur base killin ur d00dz"
