Have any of you given nicknames to the other runners you regularly encounter on your runs?

I don't know if I'm the only one that does this, but if I encounter the same person on a run more than 2 or 3 times, I assign them a nickname. Some of them are other runners, but I also include walkers, dog walkers, lawn mowers, and anyone else I see on a regular basis.

Mr. and Mrs. Mute: These two walkers smile and wave as I go by, but never say anything (I say "Morning" to everyone), and never make eye contact. They seem to be very shy, but nice.
Bouncy Smiley: She just started running recently (or at least she's a recent addition to my nicknamed list), and flashes a great smile when we pass each other.
Tower: This guy is about 6'3" or 6'4", with gray hair, and he's just built like a tower. He carries himself like one too.
Military Man: Actually, he may be a fireman. But he has that look to him. He has a very well-behaved husky that he walks in the mornings. I'm a straight guy, but Military Man is seriously dreamy.
Neighbor Man: I don't know where in my neighborhood he actually lives, but he just seems like a good neighbor. He walks briskly in the mornings, and always says hi.
Sensei: This is an older Japanese gentleman who walks slowly and deliberately, with his hands clasped behind his back. He wears flowing pajama-like clothes. There's probably a Japanese name for the outfit that is more appropriate than pajamas, but hopefully you know what I mean. I think this guy's pretty bad ass.
Ninja: She's actually a white woman with bushy blonde hair, but she wears all black. In the winter, she was in black long sleeves and long pants, and it was dark out in the mornings. Usually, I see other runners coming from a distance, but she would randomly show up on my runs with no warning, and I would barely have time to say "Morning" before she would flash a friendly smile and disappear again. Now that she's in short sleeves and shorts, I can usually spot her before she's in my face, but I still call her the Ninja.

So, am I crazy?
