One time i was playing "halo:combat evolved", the setting was on normal, and it was on the level "the two betrayals" and after the beginning where you fight the sentinals, i got outta that room and headed out and after the covenant and sentinals finished fighting, i killed the last two elites and i droppend my plasma pistol for a plasma rifle then a neddler and the plasma rifle fell on a elite's crotch and started spinning then it flew away when it stopped spinning.
