Ok, this trick is really simple so I think pretty much anyone could do it.
First go to the 4th of April 2010 and grab a shovel. Use that shovel to dig up bunny eggs. Once you have dug up the eggs you can go into your pocket and open them. If it is a bunny foil, take it to the bunny in front of town hall and if it is candy keep it for later use. When you take the bunny foils to the bunny he should give you bunny day furniture. Bunny day furniture sells for a lot of bells (money. You can take the bunny day furniture to Tom Nook and he will give you a lot of bells! Next save and go to the 31st of October 2010 but make sure it is night time first. Everyone in town will have a halloween mask on ,except for you, and Jack the Czar of Halloween will also be hiding and you need to find him. The trick to find Jack is if the person is moving its not him! Sometimes it can be hard to tell though as they may move at the last second so wait a while and then go up. He will ask for your candy. Give it to him and he will give you halloween furniture which also sells for loads of bells. So take the furniture and sell it to Tom Nook! All done! You can use this trick as many times as you want to! But be careful as your neighbours who aren't Jack may chase you to get some candy and if you don't give them their candy they will play a nasty halloween trick on you!!!
