Mine was a tabletop gaming moment when both my characters best friends were murdered.
They had been through so much together and I got pissed, I basically channelled my halfling rogues anger.
The murderer was a evil wizard who's plans we were standing in the way of.
So while fighting the wizard I ended up sacrificing my self by blowing both of us up and saving the rest of the party and the city he was trying to take over, so for my last words I screamed.
"Now die and regret all the evil deeds you have done and remember the faces of the two you murderer because that was your downfall!"
He died, I died but we screamed, cheered and hugged.
Now that was some deep stuff and for awhile, me and my character merged.
