Apparently the Flying Nun has quite the potty mouth. On a recent episode of "Jimmy Kimmel Live", Sally went head to head with Julia Roberts in a curse-off, and cleaned up. As you can see in the clip, Julia didn't really have to be bleeped, while Sally went all"Sybil" and kept the censors quite busy. Actually, had I been asked before this competition who I'd thought would win, I think I would've gone with Ms. Fields.
