Retiring captain Lawrence Dallaglio lifted the Guinness Premiership trophy after leading Wasps to victory over rivals Leicester and then declared: "It is the only way to finish".
Dallaglio, the heartbeat of Wasps for 18 years and 339 games, led the club to their fourth title in six seasons with a 26-16 triumph over the Tigers.
Wasps surged into a 23-6 half-time lead with tries from Tom Rees and Josh Lewsey and, although the Tigers threatened a second-half comeback, the deficit proved too great.
Dallaglio, who was in tears before taking to the field, departed the action on the hour to a rousing ovation from a world record crowd of 81,600.
"It is the only way to finish," said Dallaglio. "I chose Wasps because they were top of the table. When I arrived at Wasps I wasn't in the greatest place in the world.
"I had lot of issues after losing my sister the year before and I felt very much at home. I was among the right people and it was a special place. It has been for the last couple of decades.
"This club is all about the players and about the people. I have been very privileged to have had a lot of special days."
Dallaglio has won all seven Twickenham finals he has played for Wasps - four Premiership grand finals, two Heineken Cup finals and a Powergen Cup final.
"I have been spoiled at Twickenham, not just for Wasps but for England. This is a great place to play rugby. Grand final day is great. Clearly Wasps enjoy it.
"This was a phenomenal effort from everyone involved in the club. I am very proud.
"It is great to be able to call yourself champions of England. To be a great club you need to be able to win the title."
