While I was buying the guitar cases today, I asked the salesdroid if he had any gut strings for classical guitar. Though he assured me they had three different brands, I was suspicious. I asked, "Real gut, not nylon?" He confirmed, and grabbed a pack. "I don't see gut actually mentioned on the package," I said, after inspecting it closely.
"What do you mean by gut?" he asked.
"You know, 'catgut'. Sheep intestine. Like they make high-end violin strings out of."
"Ewww," he said. "No, we don't have anything like that. These are nylon." Sigh.
Also, today I bought a hole saw which proclaimed on its packaging that it would cut through metal. I wore all the teeth off it before I'd gotten halfway through the lid of an ammo box. Well, that was $11 well spent...
