I had been watching Zombieland - Double tap, and I could assess from the coincidental laughter that Tony had been watching it as well, in another room. I had drifted off in the middle and was confused by the reappearance of the pink girl.
...oh...spoiler alert...sorry..
He explained it, then started on about how he had watched the first one yesterday and was happily surprised that the second one was on today.
Tony: I can remember the first one but not the second one.
Me: You've just watched it!
Tony: No. I mean from before.
Me: Oh! You've seen it before then?
Tony: No.
