Brian Mulroney's delusions in that respect are, I suppose, as grand as his chin. ;-)

Bob Stanfield could sell underwear
And Trudeau could certainly swear
But Brian Mulroney
Just gave us the looney
Aside from a lot of hot air

Joe Clark had not much of a chin
But "Don't worry!" said Brian to him
I can take up the slack
And lead the attack
For mine's long as the road to Berlin
