hard to limit it to 3 moments and a lot of have already been mentioned... but off the top of my head -
* winning the the 1985 GF and the Mortimer brothers and their kids doing a victory lap around the SCG
* Preliminary final victory vs the Raiders in 1994 with Halligan kicking a field goal
* the 1995 finals run which saw us knock off the 2 glamour sides of the 90's, the Broncos and Raiders, and with the Raiders exacting revenge for the previous year's massacre in the GF, and then beating an awesome Manly side in the GF and holding them tryless... finals specialists
* 1998 Preliminary Final vs Parramatta... at 18-2 down, i was certain we were gone but to come back and against the Eels... incredible... i only wish Polla-Mounter's field goal attempt on the bell was successful --> would have made it the greatest 12 minutes of rugby league ever
* O'Meley and Bryce Gibbs clashing with Gibbs getting knocked out when trying to make a tackle
* our victory vs Brisbane in Brisbane in 2004... as good a regular season performance as we have ever displayed... and with Patten in the bin for 10 minutes and Tim Mander ref... an Origin atmosphere and yet we pumped a star-studded Broncos 46-18
* El Masri's sideline conversion against the Knights in 2002
* Barba in 2012... i enjoyed watching Barba that whole season as much as i enjoyed watching any Bulldogs player i have ever watched
* i forget the details now but there was a game in 2010(?) against the Roosters where we put 60+ on them including a try to Morris after a kick off which saw Martin Kennedy slip and cop a passed ball straight to the head which then got picked up by Morris who then scored
* Utai's match winner against the Roosters in 2003 after all that rubbish from them about how they were the best team of 2002
* Brent Sherwin's performance vs the Storm in 2004 finals... terribly underrated at his best and there he was vintage... made future legends (ie. Cameron Smith and Billy Slater) look second rate
* 2004 GF... 2001-2004 was hard being a Bulldogs fan as the media, public and rival fans really went overboard with the Doggie hate... literally had "experts" saying on TV that we were dead as a brand and would need to relocate in 2004... had Darren Lockyer make that "raper" joke... and yet by the end of the year we were champions... no other club in the NRL could have endured and prevailed against such pressure... the club is true steel as compared to the tin other clubs have proven to be (eg. Eels)
* i'm being bad with this one but Terry Lamb knocking Ellery Hanley out in the 1988 GF --> whatever was needed to win, Lamb would do
* Steve Mortimer playing as a substitute in the 1988 GF after having suffered a broken arm(?) earlier in the season... it was hard to imagine not watching him anymore after that... the greatest to have played for our club
* just watching Geoff Robinson run into players with reckless abandon
* Nigel Vagana scoring 5 tries vs the Rabbits
* Andrew Ryan climbing on and slipping on the bobcat at his last home game
* the sea of fans celebrating Hazem's last game
* Lamb returning for the 1996 season after the perfect send off with the 1995 GF victory because the club needed him after the ARL players broke away
great moments indicate a great club
