Humor keeps us alive. Humor and food. Don't forget food. You can go a week without laughing.

Whedon’s line treats humor not as a luxury but as a survival tool—something that helps people endure stress, fear, and the grind of ordinary life. The punchline (“Don’t forget food”) grounds the sentiment in bodily reality: laughter matters, but so do basic needs. The final twist (“You can go a week without laughing”) undercuts any inspirational tone with a bleakly comic truth—people often do endure long stretches without joy. Taken together, the quote captures a worldview common in Whedon’s writing: resilience is built from small, human comforts, and comedy is a way of facing darkness without denying it.
