found new glitch so i post
go to the boat level in DA where you have to smuggle the red mercury. go to where you start and go to the um right i believe follow it all the way. you should reach an unclimable fence and a pole right above you. youll know because sam will say "thats where i should pick up the bomb" climb the pole so that your legs are up and your head is facing the fence, go all the way till your up against the fence and cant move anymore. Sams head MUST be against the fence for this to work. now if not so put your legs up. rotate the camera with the analog stick till you basically can see the inside of Sam's head. now let go. pay atention to sam's face. if you did correctly you see him with really wide eyes and a creppy smile. if you cant see it*it happens REALLY fast so watch* either try it again and again or plug in your VHS player pop in an empty tape, set recording to AUX*or if you got a crap box one like mine it records whatever channel is on* and record. now do this. i did this so i can see it. play the tape in slow mo than pause. its creppy man. if i find pic on google. ill add to save you the trouble. remember i have DA on PS2 so i dont know if this is also on other systems *XBox, 360, PS3, PC, GC, or Wii**yes, its on the GC, hard to beleive isnt it? and try it on Wii its awesome!sorta*
