Any idea? Nope? OK, two clues.
Clue one. The little people are all proud members of the Aireborough Lions Under 7s rugby squad.
Clue two. The bigger person on the left is Kris, their head coach.
Still none the wiser?
Well, meet Kris's trusty assistants Iron Man, Spider Man and Robin - aka Dylan, Ollie and me. (Kris has a Batman suit but didn't get the message).
We held our last squad get together of the season yesterday and, as fun is the name of our game, we oldies thought we'd get the Lycra out.
Charlotte even tagged along dressed as a princess.
It's been a genuine privilege to work with such a charming and entertaining group of young men.
We regroup in September as Aireborough Lions Under 8s.
