He's so freaked that he immediately says "I was genuinely scared by that" before watching it back and descending into a fit of guffaws. 

He then manages to pull himself together to talk (briefly) about his kids and his relationship with ex-wife Jennifer Garner...

Garner appeared on the Today Show earlier had marginally more to divulge, saying: "People have been so kind to my whole family, and we really do appreciate it. But, you know what, we're doing really well. Thank you. The kids are great. They'll be getting up and going to school soon, and Ben is there and he'll be taking them. We will make it work."

It's been a rough year for relationships for the Affleck brothers; it's just been revealed that Ben's sibling Casey Affleck has just split with his wife of ten years, Summer Phoenix (she is indeed sister to Joaquin and River, in case you were in any doubt).

The couple - who have two sons together - released the following statement via Just Jared: "Casey and Summer have amicably separated. They remain very close friends."
