no offense dude, and i'm not trying to be mean, but there is a whole internet, a world wide web of information, for you to use to find out the answers to the questions you post. i'm sure that somewhere on the web, is the date of summerslam, probably even on the wwe's official website. the questions you post on this message board would be more quickly and easily answered by doing a web search on a search engine, say, google.
I just saw Samoa Joe for the first time ever live this past weekend, and he had one HELLuva stiff fight with the Necro Butcher at the Philly IWA:MS show. The way that they both were going balls-out just made me take notice.
