Name the red one Boomstick and name the other one James Dean.
trust me on this one.
My bongs/pipes/other cannabis utensils always have weird names, my yellow bong was named "Bong Tran" after my friend Phong (hes yellow), my newer bong looks like a sqaush so we call it "The Gourd", my little pipe is called Stone Phillips, and my little false ciggarette thingy is called JJ Smokes (named after an old 49ers reciever i think he plays for jacksonville now)
