1. This seems to be a good time to point out, in case you hadn't noticed, that no one in feudal Japan has asked Scott about his handgun. Or why he's white.
2. Top right panel: You knew David was going to find some way to put a furry girl in here somewhere, didn't you?
3. It's a testament to the unflappability of Texas Rangers that he does not say a damn thing about the fact that this girl is some sort of human/animal hybrid. A human/animal hybrid that looks like a member of KISS. Peter Criss, to be exact. Although I'd rather fuck Peter Criss.
4. If nothing else, it can be said that one is unlikely to find many geishas that look like this one. In addition to being some sort of weird cat-person, she also has one tiny, deformed hand and one giant, meaty man hand, and is carrying an undersized fan that depicts a plateau and a donut. That she is built like a male professional wrestler should come as no surprise, considering whose work this is.
5. The geisha doesn't actually say anything - she just sort of runs up and kisses our protagonist. Either this is telepathy at work, or she is mute, or all the dialogue that needs to happen has already done so in David's head and wasn't written down. Regardless, we finally do see her talk in the final panel, in which she delivers the momentous line, "Veeeeee."
6. Clearly visible in the rear window is a structure that may be a silo, or possibly a giant empty bottle of Tums. Until just now, there was no window behind him. It probably came from the place his mullet disappeared to.
