I've now played poker with two supporting actors from TV shows at 3-6 limit tables at the Mirage. A few months ago, it was Brad Garrett from "Everybody Loves Raymond." Last night I was sitting next to a guy I'm pretty sure was Powers Boothe, from "Deadwood" and Sin City. I also have heard Jason Alexander plays there sometimes, but I've never seen him. I don't really have a story to tell, I just think Powers Boothe is cool enough that I should post about it. And if it wasn't him I was playing with earlier, well, that guy sure looked a lot like Powers Boothe, which is kind of interesting in its own right, I guess.
In case you actually care: Here is some evidence I found that Powers Boothe might actually play poker, which makes me feel somewhat more confident it was really him. (Search for "poker." It's a bit more than half way down the page.)
