That sounds like Carlin, but Carlin dispensed much wisdom in his time.
My favorite story from Jack Marigold's A Child's Garden of Grass goes something like:
A drunk, an acidhead, and a pothead are walking through the woods. As it becomes evening, they come to a city surrounded by a wall, and in the wall is a closed door with a sign that reads: "This door is only open 9-5". After knocking and getting no answer for a few minutes, the drunk shakes his fist and says, 'let's smash the door down!" The acidhead peers at the doorknob for a few minutes and says, "let's just float through the keyhole." The pothead shakes his head and says, "naw, man; let's just sit here and wait for it to open in the morning."
I can't handle pot; makes me super nauseous for the entire time I'm high. Always has. But I love the people.
