A feral Billy Casper doing blue-tit like acrobatics on a cross bar during a school football match.
Sadistic PE teacher, Mr Sugden, played by a red-faced and barking mad Brian Glover, who imagines he is Bobby Charlton and cheats. The brutality of the cold shower he makes Billy take.
And the bird, hovering on the wind above fields on the edge of a South Yorkshire pit village. Kes, the 1969 adaptation of Barry Hines novel, A Kestrel for a Knave, by Tony Garnett and Ken Loach is one of the greatest British films ever made, and the scenes have stayed with me for decades.
