Huh?

Some people are so spacey that you wonder how they made it to adulthood without losing life or limb to some bizarre accident brought on by their own absent-mindedness/lack of common sense.*

Ridiculous conversation #1
Spacey friend: How's this for a quote? "In the land of the blind, the one-eyed man is king."
Me: What's a one-eyed man doing in the land of the blind? He can still see.
SF: Well, how about this? "In the land of the mostly blind, the one-eyed man is king."
Me: But if they're only mostly blind, then there might be other one-eyed men, which would erase the advantage held by the one-eyed man in your original quote.
SF: Oh. Hmm.

Ridiculous conversation #2
Co-worker: (leaving the office) Have fun playing poker. (To another coworker) Don't let him call just so he can see what cards other people have.
Me: (to SF) You call just to see what other people have?
SF: Yeah. (Shrugs)
Me: Why?
SF: I dunno, I'm just curious.
Me: Curiosity killed the cat.
SF: What does that mean?
Me: It's an expression...you know, like if you're too curious...never mind. Do you call to see what people have so you can see if they have tells?
SF: Nope, I just want to see what they have.
Me: Er. Don't you want to at least try and win?
SF: It's like a $2 buy-in. I'd rather know what people have.
Me: But you don't gain anything from knowing what they....oh, forget it.

Ridiculous Conversation #3
Me: (looking at a Google map) Hey, SF, you're from Houston right?
SF: Yeah.
Me: Can you explain why Google's telling me to take this route back to my apartment, but in the morning when I drive here, it just tells me to take this route? Couldn't I just take 288 south all the way back? Is there some wacky reason I have to go home a different way than I came?
SF: I dunno. Maybe the Loop only goes in one direction?
Me: Maybe...wait, what? Highways don't just go in one direction.
SF: (Shrugs)
Me: Riiight...

*Like the lady who set her apartment building on fire trying to light a candle. She was out of matches, so she used the stove to light a towel on fire, carried the flaming towel to her bedroom, and attempted to light a candle which was sitting on her bed. I mean, I guess she succeeded in lighting that candle...
