It's fun and games, plus a tiger.
In an episode of Fort Boyard, a French game show, Parker pedals a caged cart between where Diaw and fellow NBAers Ronny Turiaf and Nicolas Batum refill the cart's water gun, so that Parker can then shoot it into some sort of funnel.
All the while, he shares space with the tiger.
We're not sure what's actually going on, but it looks like fun—aside from the fact the enclosure looks reminiscent of Roman fighting pits, large cat and all.
But you do you, Tony.
