Richie Sambora might not be that far removed from Bon Jovi after all.  Frontman Jon Bon Jovi took the ALS Ice Bucket Challenge over the weekend, and after he was doused called out his bandmates - including the group's estranged guitarist.

Jon Bon Jovi is among a fast-growing group of celebrities who are allowing themselves to be drenched with ice water to help in the fight against amyotrophic lateral sclerosis, better known as Lou Gehrig's disease.  Other stars who've recently taken on the challenge include Justin Bieber, Taylor Swift, and Justin Timberlake.
