D2 trivia generation for "quiz"

[Thrugg]

Trivia Question: you buy a couple items from a shop, mess with them a little, and then sell it back to the shop at a profit! What did you do?

I recall there was a bug in the original 1.10 release (no idea if it has been fixed since on the realms) where you could equip a weapon with the Grinding prefix on a high level char and it would then sell for more than you paid for it (because in the shop it displays as if it was on a level 1 char). You had to sell it using the "Sell Item" interface (rather than dragging and dropping) which made it too inconvenient to really farm it, but I think it would satisfy this question.
