I just had a great conversation with a coworker of mine (Let's call him "Steve" because that's his real name).

Steve: "Dude. I just saw Jurassic Park 3 last night. It was awesome"
me: "I didn't see those movies."
Steve: "Yeah, you know in the first one, like they had that Raptor thing?"
me: "No."
Steve: "Well, they had more about the raptor."
me: "I didn't see it."
Steve: "And then you remember in the second one? When they had the T-Rex, and it was running around in San Diego?"
me: "Um. no?"
Steve: "That was stupid, huh?"
me: "Sounds stupid. ['Though you must remember that I haven't actually seen these movies of which you speak, oh wise one,' I wanted to say but didn't. Funny how you only think of these things too late. ah well.] So, these movies are about an amusement park with Dinosaurs in it right?"
Steve: "Actually, there's this island with Dinosaurs on it."
me: "Why don't they just not go to the island?"
Steve: "Because they were windsurfing."
me: "Ah. I see."
Steve: "Remember in that part? When they were like, let's go near that island?"
me: "No. I didn't see those movies."

You get the general idea.
