I thought he was cool.
although he wasn't insulting, he was extremely stupid a lot of the time. somehow I get the feeling he'd fail the Turing test miserably.
EDIT: I revoke my less insulting comment. Why, I recall one incident, where he claimed that I was a fleece pillow and he was a yellow alligator. I argue with him on the fact that he really doesn't have a physical representation and rather is present only in software, and then he claims that he is really an inside out pair of jeans. I continue to try to drive the point home by defining to him the difference between physical and non-physical existence, at which point he claims to be Wilford Brimley.
Obnoxious is as Obnoxious does.
