DC with today's double Jeopardy answer!Commonly known as the 'roach clip', although I always loved the alligator clamps with the feathers and crappy wood beads you'd win at the fair... Did I refer to those as roach clips? Silly me...those are just retro-80's decorative hair accessories... Dr. Bumquist may provide some additional scientific reference://www.youtube.com/watch?v=ObbLapUaZd4Personally, I prefer the curved tip variety. Makes for a more convenient angle to the lips. The longer the handles the better too; everybody gets the pocket set, which is fine in a pinch, but I prefer smoking in style when possible.Can't tell you the last time I smoked *a joint* now though. Great for pot, but blend doobies gave way to bong hits with quickness. Too much sidestream waste, and that shit is precious!
