Why is Bob late?

M: Hello, Angel. Sorry I’m late.
W: Where were you, Bob7 I was beginning to worry.
M: I was on my way here, and I saw a crowd of people. They were standing around a tall fellow and they had pens and notebooks. Someone explained to me that they were getting his autographs, so I handed him my notebook and pen and I got one too.
W: One what?
M: An autograph. Look!
W: Can I see that? Wayne Gretzky. You got Gretzky’s autograph!
M: Wayne Gretzky?
W: He is the best hockey player in the world, Bob.
M: Is that true?
W: A lot of hockey fans think so.
M: What else do you know? Let’s go, and we can still catch the game.
