Geek thing. Back in the 90's worked on Unix systems and was trying to find a way to combine that with my Jeep being a YJ. At risk of boring some to tears... the /dev directory on a Unix box is where the device drivers are stored for things like the video card, hard disk, etc. So, /dev/yj translates as "the YJ device" or "Jeep". Sometimes folks get the /dev part, other the YJ part, but takes Jeep geek and computer geek to put them together.

Many, many years ago, on a not-to-be-named, not-exactly-legal trail, I slipped off a rock going up hill and backed hard into a tree (thankfully, otherwise could have gotten nasty) putting a pretty good dent in the lip of the tub and ripping the license plate off. One of the folks watching said "Oh no, he's destroyed the device directory. He'll have to rebuild the machine."
Was driving on Wade Ave. when a car came up next to me, a hot chick hanging out the passenger window screaming "Does that mean what I think it means?" I said "Yeah, it's a Jeep". She grinned and laughed. Should have married that girl...
The M416 trailer tag is ../M416 so can haul it behind the Dodge too which is /dev/ram. The BBQ pit is /dev/bbq. Yes, I think I got carried away. My son is thinking of getting /dev/gti. Yes, he's a geek too.
