"When Chekhov saw the long winter, he saw a winter bleak and dark and bereft of hope. Yet we know that winter is just another step in the cycle of life. But standing here among the people of Punxsutawney and basking in the warmth of their hearths and hearts, I couldn't imagine a better fate than a long and lustrous winter."
..."You're a sucker for French poetry and rhinestones. You're very generous. You're kind to strangers and children, and when you stand in the snow you look like an angel." Say it with me now: Awwwww!
Also qualifies as a Tear Jerker: After Phil has ice-sculpted a facial likeness of Rita:
Rita:(after seeing the sculpture) It's beautiful... I don't know what to say.
Phil: I do. No matter what happens tomorrow, or for the rest of my life, I'm happy now... because I love you.
Rita: I think I'm happy too.
They kiss, and Phil looks up at the sky to see snow falling... a sign that his personal nightmare might at last be coming to an end.
Another heartwarming Tear Jerker: Instead of simply ignoring the homeless old man like he initially did, Phil becomes more compassionate, and does everything possible to try and save the poor old man, or at least make his last day a nice one. He tries taking him to the hospital, he gives him a hearty, delicious meal with hot soup and rich pastry, and even (presumably) learns advanced CPR for the sole purpose of saving his life. It doesn't work, but after that moment, Phil learns to appreciate and value other people much more than he did.
He does make a point to catch that one little boy who falls out of the tree every day - even though he knows full well the kid isn't even going to thank him.
Not just that: Every nice thing he does for people is done without any lasting consequence. He does them knowing that it doesn't matter because their existence will reset in a few hours. All that matters in the end is that, at that moment, they needed help, and he helped them. How's that for benevolence?
And when Phil realises that he has woken up at 6 am on February 3: "Do you know what today is?... Today is tomorrow. It happened."
