It's scary how our minds work

Transcript of an actual exchange between my sister and myself:

To: Sis
From: Dana
This is fangirly, but I think it's kind of cool that Ralph Fiennes' nephew is playing young Tom Riddle in the Harry Potter movie.

To: Dana
From: Sis
Did Ralph Fiennes play Voldemort?

To: Sis
From: Dana
are you messing with me or do you really not know that Ralph Fiennes played Voldemort?

To: Dana
From: Sis
I assumed he did, since you said that about his nephew, because that's why it makes sense for him nephew to play Tom, but I can't pick Ralph Fiennes out of a lineup. I really only know a few Harry Potter actors- Richard Harrison, Alan Rickman, Dame Maggie Smith

To: Dana
From: Sis
Harris, I mean. See? I'm hopeless

To: Sis
From: Dana
Richard Harris hasn't been Dumbledore since Chamber of Secrets, since he's, y'know, dead and all. But seriously? You can't recognize Daniel Radcliffe? Emma Thompson?

To: Dana
From: Sis
I recongize him, but if someone says "Who plays Harry Potter?" I can't answer. Same thing with the red haired guy who plays Ron. I've heard of Emma Thompson, but I don't know who she is, in HP or in real life. I know Gary Oldman, but only because I saw "Rosencrantz and Guildenstern Are Dead," which is pretty much a three man cast. Please, are you surprised? I'm the queen of "that guy who was in that show with the rother guy and that woman."

[Dana's phone rings; caller ID indicates Sis' extension]
Dana: Yeees?
Sis: Was she the one married to Kenneth Branagh?
Dana:Yeah, but not when he was in Harry Potter. And they weren't in that one together anyway, since she didn't come until the third one.
Sis: Oh. I didn't realize he was in Harry Potter; I was thinking of the Shakespeare movies.
Dana: They were in Much Ado together.
Sis: I never saw Much Ado. I saw Henry V. Weren't they in all of them together?
Dana: I don't know, I only saw Much Ado About Nothing. Which, as Shakespeare movies goes, was kinda...well, it had Keanu Reaves, so...But it had that guy from House, too. Except back then, he was "that guy from Dead Poets' Society," the one who killed himself. In any case, Robert Sean Leonard was in Much Ado.
Sis: I don't watch House, but I know it. Roommate used to watch it, but it made him start getting all paranoid when he got weird symptoms, so he stopped. He's the British guy.
Dana: Well, that's Hugh Laurie. I'm not talking about the guy who plays House, I'm talking about the guy who plays Wilson, and the actor was the kid in Dead Poets' Society who killed himself. I mean, that's not the plot of the movie, but he was that guy. Honestly, I am constantly seeing people on, like, CSI or Law and Order or whatever and being all "Wait! That's Little Girl God! She can't be a teenaged killer!"
Sis: Everyone is in Law and Order. Whenever we go and see a show, we have a contest to see if anyone can find someone in the Playbill who wasn't in Law and Order.
Dana: Heh. When I saw Chicago, last month, Tom Wopat was Billy Flynn. Luke Duke can sing, y'all!
Sis: When I saw it, that other guy was playing him. The one who's dead.
Dana: Robert Urich. Wasn't Bebe Neuwirth playing Velma?
Sis: Maaaybe.
Dana: You don't know who Bebe Neuwirth is, do you?
Sis: No, not really.
Dana: Lillith, from Cheers.
Sis: Oh, OK. Yeah, I think that was her.

The part that is somewhat disturbing is that the only reason I couldn't identify who 'the guy in that show with the other guy and that woman' was, is because she didn't really have an actual person in mind. Personally, I plan to curl up on my couch at home tonight to watch that show with the guy from Dead Poets' Society (not Robert Sean Leonard, the other one), the guy who later did Six Feet Under, Benson and the woman from Desperate Housewives.
