In case you hadn't noticed, we have. Today marks the harmonic convergence of month and date with the universal daily call to smoke up at the appointed time. In other words, today at 4:20 o'clock on the date 4-20-2007 there will be an even more massive smoke in than occurs daily at this time. As added inspiration, I include a sample from Build This Bong: Instructions and Diagrams for 40 Bongs, Pipes and Hookahs with text and illustration by Randy Stratton.
