Mad Shopkeeper in Thorntail Hollow
In Thorntail Hollow, get a few Scarabs and go to any item and go below ten Scarabs of the price of the item. accept and he will say "no thats too low" or something like that repeat and after 3-4 times he will say: "get out i dont sell to cheapskates!!!" this doesnt do anything but its fun to watch him have a meltdown.
