The Baldwin family of actors consisting of Alec, Daniel, William (Billy), and Stephen.
Dave Foley provided the voices of all of the Baldwin brothers.
The Baldwins all appeared in their underwear or wrapped in towels beside their pool before being bombed. Billy Baldwin had unusually shaped bright blue eyes.
They all appeared to be whiny, egotistical and self-centered. Even after all his brothers are killed, Stephen didn't seem to care, simply shouting, "Haha! You missed me!" before being bombed himself.
All quotes are from South Park: Bigger, Longer & Uncut.
–Baldwin residence. No, this is Billy Baldwin. If you want Daniel Baldwin, call his extension, stupid!
–Hey Alec, do you know what sucks about being a Baldwin?
