Lynch is an advocate of Transcendental Meditation, popularized by the Beatles in the 1960s and now used for treating post-traumatic stress, depression and other afflictions. Proceeds from the comedy show will go to the foundation's initiative "to bring stress-reducing, evidence-based meditation to veterans who suffer from post-traumatic stress disorder."

The David Lynch Foundation was launched in 2005.
