oh yeah, and the simpsons episode where the kids ask homer why he doesn't have any pictures of maggie, and he says he does, but he keeps them where he needs them most (at work).
that's a bit of a heart tugger too, but again, it's because homer is so damn endearing.
what i really don't like is when they lay it on way too thick with the emotional stuff and you snap out of the moment. i felt that away about return of the king. after the battle it just goes on and on plucking the heart strings, i ended up thinking, "for god's sake, get on the damn boat".
