Replying to Tony hawk proskater 4

i was looking up cheats for this game, and i came accross one that said "if u go over to the bum who wants the birds off the power lines, and u go above the power lines, and do the combo thing to do a 900, u will get electricuted, and then u will turn into a zombie, and then if u crash on the grass, everything turns realy old." ive been trying this for ever now, and i think the guy who put this there just wants ppl to waste there time, has anyone here done it?
