you beat deja vu by doing the elvator thing but you have to make it thicker. Everytime your guy respawns from death he will remain in the same height of where your elevator is because of it's thickness :P.

after you out the fishing rod onto the stump thing you click the parasite and when it is on the fishing rod, you have to click the reel a few times and that will launch it into the backyard of the grandma or the woman.
