The ALS ice bucket challenge is pretty much conquering the world.
Ronaldo has thrown the gauntlet down to Beyonce, Lil Wayne and J-Lo, and the mischief-maker wreaked a bit of havoc as he ran around the Real Madrid training complex, or wherever, in his jocks.
Here, his teammate Marcelo takes a soaking for a good cause with his Portuguese-speaking scantily-clad buddy doing the honours.
Before plunging into the icy depths, Marcelo nominated Brazil teammate, and Barcelona rival, Neymar to risk hypothermia too.
He also nominated Brazilian TV presenter Luciano Huck and Brazilian actor Paulo Gustavo.
