Ben Affleck is one of the latest celebs to have accepted the ALS ice bucket challenge, helping to raise awareness by his pool with wife Jennifer Garner on Monday, receiving his dare from director Tyler Perry.
Before being doused, the star of the upcoming Batman v Superman: Dawn of Justice said he was going to both take the challenge and make a donation to the ALS Association.
"I guess I have to pick four other people so my people are going to be folks who I know from firsthand experience look good in a wet T-shirt," Affleck joked.
He then nominated Jimmy Kimmel, Neil Patrick Harris and, of course, Matt Damon.
He also nominated a fourth star to take a frozen shower.
