The former Manchester United boss provided the banter at Gleneagles.
You can tell Sir Alex Ferguson has been enjoying his retirement.
Since hanging up his managerial boots at Manchester United, the Scot has fared considerably better than his old side, being pictured at high-profile events all over the world.
The latest is this year's Ryder Cup, where Ferguson spoke to the European team - and their caddies.
And the former United boss couldn't help himself when he found out Lee Westwood's caddy, Billy Foster, was a Leeds fan, nor could he resist taking digs at Liverpool fan Thomas Bjorn and Arsenal supporter Ian Poulter, according to Paul McGinley.
"Billy Foster right now is a big Leeds United fan and I think Sir Alex said to him that he got 17 players from Leeds to end up at Man Utd and that bit hard when Billy had a go," European Ryder Cup captain McGinley is quoted as saying by the Daily Mail.
"Billy let him know what he thought in no uncertain terms. I think the caddies enjoyed he was standing up to Alex Ferguson in this room full of all his peers.
"It was just a bit of banter and in fairness to Sir Alex, he's used to this. He's in the dressing room and he's in that banter all the time. This was very normal for him.
"But the biggest stick was Thomas Bjorn being a Liverpool fan and a lot of stick to Ian Poulter for being a big Arsenal fan."
In reality, Fergie only signed three Leeds United players, although they each would have hurt the Elland Road faithful in their own ways, as Eric Cantona, Rio Ferdinand and Alan Smith traded Leeds for Manchester.
