Is there a bell cheat on Animal Crossing on Wii

Yes there is!
Go onto the wii menu and change the calender to year 2000. then go onto animal crossing and select your character and start playing. as soon as you get into the game, save it and quit! then, go onto the wii menu again and change the calender to year 2035. then start playing animal crossing again, as soon as you get into the game, check your mail box and there should be a letter from the bank saying you've earned 100,000 bells in interest! this will also come with a box of tissues as a present attached to the letter!
the only problem is, that when you change back to your current year, i.e - year 2010. once you start the game, there will be weeds in your town and your hair will be a mess!
