What better way for Eminem to end his Monster Tour with Rihanna than by taking the ALS Ice Bucket Challenge live on stage in his hometown of Detroit?

Eminem jumped to his feet after getting soaked, and didn’t hesitate to say that he would never have allowed it if it wasn’t for charity. Credit: YouTube/Rita Brezovay
