LOL! According to a post on AllThatChat, unintentional hilarity ensued at the Barrymore today:
"There was hilarious (and completely in-character) ad-libbing during the first scene of Speed the Plow this afternoon, when a doorknob fell off late in "Act I" --
Esparza: They don't make studios like they used to.
Esparza throwing the other half of the doorknob through the doorway.
Piven: Thanks for fixing my office.
Esparza: F.U.
The actors were having a hard time concealing their own laughter, and the audience loved it."
Sarcasm is an allergic reaction to stupid people.
