Wally approaches a man and a woman who are smoking. He says, "Here's my first cigarette ever. I'm looking forward to the many smoking breaks I'm entitled to." Wally says, "I'll probably see you three times a day, just smoking and chatting and enjoying the fresh air!" Wally says, "I assume you light the color-coded end, right?" The man and woman drop their cigarettes and say, "I quit."
