Bum Rock

Me: “Hey, Troy, do you see those two rocks over there in that yard that look like a bum sticking up out of the ground?”
Troy: “No.”
Me: “Those pink ones that look like two bum cheeks being burned by the sun.”
Troy: “They do not look like a bum!”
Me: “Sure they do. In fact, that’s actually known as Bum Rock.”
Troy: “No, it’s not.”
Me: “It is! People come from all over to see it. It’s even on the map that way. It’s a landmark, like on a treasure map. That’s it! Bum Rock is where pirates bury their booty! Get it? Bum? Booty?”
Troy [rolling his eyes, while struggling not to grin]: “Dada!”
