Browsing the visitor stats today, I found this little gem:
"Mozilla/1.22 (compatible; MSIE 2.0; Windows 95)"? Who uses such a browser? My bet is on it being a zombie machine that somebody has completely forgotten about, which would explain the several other hits I have from versions of IE before 5.0... These visitors turn up, hit the same page repeatedly, and then leave. Unfortunately I deleted my spam before seeing this, otherwise I'd be able to verify this theory. Maybe I'll look more closely next time.
