Fishing was a sort of semi-scam that The Eds did in "X Marks the Ed." The goal of the scam was to catch fish in Ed's backyard pond and sell them to a fish supplier for a nice sum of money. While the scam itself was not aimed at the kids, it was still intended to make a profit. The only problem though was that they were fishing in a spot that most certainly had no fish in it, as pointed out by Edd. However, Ed did catch something though. While trying to fish, he ended up finding his lost freezer experiment that Sarah hid. When he tried to reel it in, though, its immense weight sent The Eds flying out of their boat, and the scam was ruined.
