Captain Kirk from Star Trek stopped by my place the other day and I didn't think much of it when he asked me to borrow my new helix ruler to help him through a class the Neutral Zone, the Klingons and Romulans were able to evade the Klingon and Romulan patrols. Kirk and my ruler were only five minutes alone when I heard the most terrifying sound - like a million acrylic particles screaming in terror before suddenly stopping. As I stormed back into the room, imagine my horror to see a sweaty Kirk grinning madly, his wild eyes lit by a bright streak of light, clutching a piece of a broken helix in each hand. Study the inscription on it carefully. And then it hit me. Turns out she wasn't Shatnerproof (let alone proof). Read the fine print carefully! good for drawing straight lines (wavy edge) or measuring objects (sensitive to heat and cold) - and that was before recent events. Who knows, maybe it was these flaws that triggered the recent events mentioned? however, report that a sharp acrylic shard is just right for an emergency tracheostomy with a Bic Crystal pen shaft, as it can pierce even the toughest trachea.
