I was ten the first time I heard the classic Cheech and Chong bit “Dave’s Not Here” on a record owned by the stoner older sister of my best friend. At the time, my child mind could not grok why this somewhat tedious riff was funny at all in any way. Now that I’m older and more experienced, I totally get why “Dave’s Not Here” is pure comedy gold, and possibly the most brilliant piece of stoner comedy every created. Just being serious.
