Notable Example: Harold & Kumar Go to White Castle (2004), Harold & Kumar Escape from Guantanamo Bay (2008)

The great absurdist moment of the first Harold & Kumar film involves one man and his passionate love for a bag of weed. Not his love for weed, but truly his romantic feelings of devotion for a single bag. It's part l'amour fou, part Raging Bull, and all beautiful.

No more words, just let Heart's "Crazy on You" take you away.

 (Note: The joke is reused in the sequel, but it lacks the novelty and punch).
