Hi, I'm Random

It's interesting how many people introduce themselves saying something like
"I can be kind of random sometimes."
"just as a warning, don't get weirded out by the stuff I do."
"The more you get to know me, you'll see how strange I can be."

ok, that's great. Just about everyone can say that, so you're really not saying anything unusual.

If you really want someone to know that you're random, here's a tip I learned from my 2nd grade English teacher: why not show them instead of tell them?

e.g.
you: "Hey, have you been to Nicaragua?"
other: "No, why? Have you?"
you: "No, I haven't either, but I think it would be really cool to go there someday."
other: "Cool! Why Nicaragua?"
you: "oh, I just think it would be really cool to learn enough of the language to run into as many barbershops in Managua (that's the capital!) as I can, yelling "Don't panic! The aardvarks haven't escaped yet!"
other: ... "uh, why Nicaragua in particular?"
you: *stare at them incredulously, as if they just asked a really stupid question, and then move on to the rest of your introduction as if you couldn't be bothered to answer that question*

Wouldn't that make things so much more exciting? And actually prove that you're random without having to tell them?
