In what episodes does tony look at ziva's butt? Can you please list them

Well, I might be forgetting some, but these are the ones I remember right off:

Silver War - season 3
Voyeur's Web - season 3
Singled Out - season 3 or 4, can't remember
Driven - season 4
Judgement dia - season 5

Probably mais episodes, but this is all I know of at the moment. Hope it helps. ;)
