Good grief. I just spent ten minutes trying to help some teenager pick out an appropriate sewing needle. She said she wanted really thick and preferably sharp. I figured she was doing some bookbinding or leatherwork. Finally she settled on a tapestry needle. “What are you using it for?” I asked. “My friend’s going to pierce her own tongue.” “GAHHHHHH,” I groaned. “Don’t use that one. It’s as blunt as a ball-point pen.” And then I mentally barfed. I cringed enough watching a professional pierce Adam on Mythbusters; I can’t imagine the idiot that would try to do it themself.
