To get this trophy, go to the Lodge; a fish is located on the right wall of the bar. Interact with the fish 25 times to hear his jokes. The problem is that once you interact one time, you have to wait for it to do it again. This is the best strategy to get the 25 jokes quickly: Please interact with the fish mentioned before, then travel to Cursehaven- Withernot Cemetary and go from where you spawned, climb the set of stairs on your right, and jump down before crossing to the other side. Once you're on the ground, you should see a light coming out of a building. Go to that light, and you should see another fish.  Now, repeat the formula, Lodge, Cursehaven- Withernot Cemetary.
