Kino der toten Glitch for more bonuses.?

Ok there is a glitch on call of duty black ops for ps3 that if you jump on your partners back you and him get downed but you get more bonus items such as nuke and things like that but we Only know the first one. There are 3 spots you do this but we only know one. Can anyone tell us or find a youtube link for us that explains were these are?
