Anytime I spend a significant amount of time with my Dad in his natural environment, we always end up getting in these absolutely pointless debates over irrelevant trivia. He likes to think that he knows everything, which is sometimes in direct opposition to my actual omniscience. Case in point:

The scene: his apartment, beer in hand, flipping through the various movie channels. The remote settles on the terroristic cinematic offering of Die Hard.

Dad: (offering an editorial) This movie is stupid. They make the cops out to be nothing but idiots.

Me: (concurring) Mmmm-hmmm.

Dad: Why wouldn't he just shoot Huey Lewis right then?

Me: That's not Huey Lewis, it just looks like him.

Dad: That is too Huey Lewis.

Me: No, it's not.

Dad: Yes it is, that's Huey Lewis, look at him.

Me: Dad, I guarantee you, that's not Huey Lewis.

Dad: You don't know what you're talking about. How old were you when this movie came out?

Me: That's not the point, it's--

Dad: How old were you?

Me: How many times have YOU seen this movie, huh? S'what I thought.

Dad: *I* remember when this movie came out, there was a big deal made that Huey Lewis was playing a terrorist.

Me: ... That's NOT Huey Lewis! It just looks like him! I've seen Huey Lewis in a movie before, and he has a different chin! Plus he sounded completely different from that guy! Are you trying to tell me that he's had extensive reconstructive surgery since then?

Dad: It is so Huey Lewis.

Me: I can look it up on the internet, you know.

Dad: (does this dismissive thing by arching his eyebrows and taking a sip of beer.)

Me: (looks up information on internet.) See, it's SO not Huey Lewis! It says here, "Huey Lewis-looking terrorist"!

Dad: OK, but does it say who it is, then?

Me: (scanning info) No...

Dad: That's cause it's Huey Lewis. That's Huey Lewis, and that's the detention supervisor from Breakfast Club.

Me: You mean the principal.

Dad: No, detention supervisor. From that Breakfast Club movie.

Me: I know, he was the principal.

Dad: He wasn't the principal, he was the guy who watched them while they were in saturday detention.

Me: (incoherent disbelief) ...aka, the fucking Principal!

Dad: The principal wouldn't show up to saturday detention!

Me: Neither would the kids! There's no such thing as saturday detention! He was the principal! That's how come he knew Judd Nelson and kept giving him a hard time! Why would a detention supervisor even care? GOD! When did you become the expert on 80's movies?

Dad: How old were you when that came out? Hmm?

Me: He was the PRINCIPAL, and that's NOT Huey Lewis. I SWEAR.

Dad: Mmmm-hmmm. (changes channel to The Fifth Element.)

Me: Look, Bruce Willis again.

Dad: Oh, I saw this one on an airplane one time. Where he's a taxi driver in the future? This movie is stupid.
