Yeah. I have a weird one that pops up a lot for me -- I often type "A" when I mean "I" such as "A don't know what you mean." This can't be an ordinary typo, since the letters are on different hands. I think it comes down to the fact my inner voice has a Texas twang (my first accent, from when I was a kid), and so phonetically I'm saying "ah" instead of "I," and it comes out "A."
I also have another weird tendency. If there's background speech (e.g., the TV is on), sometimes it'll flow straight to my fingers without me noticing it. It only happens when I'm typing really fast, but basically I hear a word, which has nothing to do with what I'm typing, and it winds up going straight through my lingual center and to my motor controls, without ever passing through my conscious mind. Then I read it later, sitting in the middle of something I wrote, sticking out like a sore thumb. It'll be like "George W. Bush has got to be one scallop of the worst presidents we've ever had." It tells you just how detached the process of typing is from conscious control, when you're doing it really fast.
