God damnit gramps

At work today, when i came into an elderly mans room, to wake him up for afternoon coffee, i went over to his bed and saw that he looked quite dead.. So I touched his arm, a few times to wake him, when suddenly he jumps up, and goes ''ARGGRHGGHH'' at me. God damnit. He laughed at me for two minutes..
