the bit at the end of the second series of doctor who where rose "dies".....that ALWAYS gets me.......when they're on the beach saying goodbye.
Also in ER when Mark Greene died of a brain tumour, that got me
Oh, and the bit in Armageddon when Bruce Willis pushes Ben Affleck back into the lift and tells him that he loves him and always thought of him as a son......then back on earth when William Fichner meets Liv Tyler and says "Colonel Willie Sharp, United States Airforce, ma'am. Requesting the permission to shake the hand of the daughter of the bravest man I've ever met"
There's probably more too, but I can't think of any mor right now........lots of things get me tho......i'm a big sissy
