Simon Helberg's Strange Acting Secret with Hugh Grant

On Thursday's Conan, The Big Bang Theory's Simon Helberg revealed his and Hugh Grant's

surprising tricks to relieving anxiety when acting. When filming Florence Foster Jenkins, he learned Hugh Grant carries around something called a "panic sack." The oddly named bag contains homeopathic remedies that are said to calm the nerves.

Though he does not have a panic sack of his own, Helberg explained that he also has an odd place to keep his anxiety remedy. Helberg said, "My wife had given me all of these little like cocaine vials of essential oils."

Thankfully, Helberg doesn't have cocaine in those vials. Cocaine isn't known for calming the nerves.
