Luffy hitting Saint Charloss. I actually reloaded that scene about 3-4 times to enjoy every drop of satisfaction :)

The other would be Usopp rejoining the crew. To be precise, the very second Zoro "accepted" him with a mere smile. Very touching, you think you will shed a (manly!) tear, but in the end you can't help but laugh it back (because of satisfaction).
