British Bulldog for the WWF European Championship, officially making Michaels the WWF's first Grand Slam Champion. On-screen, the name was taken from comments by Hart, who on several occasions, particularly including the October 6, 1997 episode of Raw Is War, had labeled Michaels "nothing more than a degenerate". The following week, on October 13, 1997, Michaels made "D-Generation X" the group's official name, mockingly citing Hart's insults as his inspiration and how Generation X (with both members being part of Generation X) is always stereotyped as apathetic and cynical. Although DX and the members of the Hart Foundation continued to battle on-screen in one fashion or another through the end of 1997, the Bret Hart-Shawn Michaels feud ended abruptly at Survivor Series when Michaels won his third WWF Championship via the Montreal Screwjob, whereby Hart was lied to about the match's pre-determined outcome after Hart had signed with World Championship Wrestling (WCW) and refused to drop the WWF Championship to Michaels in Canada and instead agreed to drop the title one month later in Springfield, Massachusetts. Rick Rude was also legitimately upset over the events of the screwjob, and subsequently left the WWF to return to WCW. On the November 24 episode of Raw Is War, DX invited Jim "The Anvil" Neidhart to join the group which he accepted prior to a match later that night between Vader and Michaels. Michaels, Chyna and Helmsley assaulted Neidhart at the end of the show after Michaels defeated Vader showing that Neidhart's invitation to the group was nothing more than a ruse. The following week on the December 1 episode of Raw Is War, Helmsley defeated Neidhart. After the match, DX assaulted Neidhart once again, before Michaels spray-painted "WCW" on Neidhart's back, and signifying him following Bret Hart and The British Bulldog to WCW. Sgt. Slaughter and Ken Shamrock saved Neidhart, before Slaughter and Shamrock attacked DX at the end of the show. D-Generation X was used as the title for a WWF D-Generation X: In Your House pay-per-view telecast on December 7, 1997. By this point, with Michaels holding both the WWF and WWF European Championships, and DX's victory in the feud with the Hart Foundation, their status as the lead stable in the company was solidified. Michaels headlined the event and was disqualified in a WWF Championship title defense against Ken Shamrock when Owen Hart interfered, having not been seen on
