George Carlin's 3 Free Jokes

Last Saturday we caught George Carlin at the Sac Civic Center. Carlin, who recently turned 70, is still on top of his game. He gave the audience "3 free jokes" to share with others, which have been posted below. The best part about the show was the Sign Language interpreter, a rotound middle-aged woman, that had to flip-off the audience every time Carlin dropped the F-bomb. Can you guess what she did each time he said "jerk off"?
