Guess You Better

SGM: Can I use your copier?
Me: Yes, you may. But you have to listen to my "Mustang Sally" story.
SGM: How did you know I was copying "Mustang Sally?!"
Me: It's in your hand. Anyway, there was this restaurant near where I grew up called Grandma Sally's, and every time we passed it we'd say "Guess you better slow your grandma down." Every time. And we laughed every time.

SGM: Some things never get old.
Me: Ayup.
