In the Traditions Of The Trade level where you have to kill one of the brothers in the sauna, there is a way to kill the same person twice. Bring a weapon into the sauna once Mr. Speedo enters the Sauna. Kill him with whatever you want, but do not kill him with the steam. Leave his body in the room and leave the sauna. Besides the sauna door is the knob you where supposed to turn to kill him. Turn the knob and an intermission sequence will show him alive, well and sweaty again, but shortly to die once more.
