Oh that is perfectly normal. In France where this was taken, it is how the coaches show respect for the best player on the team. Notice how the strings are undone, and how the player has his hip out front? That is how he communicates to the coach to put his hand in there. He could even go as far to put his right leg back, that would mean the coach would have to drop to his knees.
This all is very very very factual, if you dont believe me, go find yourself an unicorn.
Found one.
Nice tusk.
That's a whale though..
However, you believe me?
I was making fun of how tusks from narwhals were used and sold as "unicorn horns" to royalty and other poor suckers.
Jiro..at least I didnt get to do that when you were visiting! lol
