Steve McGarrett is one ungrateful SOB!!!
Danno saves your life first by performing a miracle of a plane landing on Waikiki beach without so much a scratch! :D
He then saves your life a second time by agreeing immediately to giving up a piece of his liver and the next several months to a year of his life! XD
...And all you can do is complain and belittle him egregiously and extraneously like a little bitch like always!
If Danno were me, I would be like "Don't want my liver? Give it back then!" Then proceed to drive a scalpel into his torso and rip the liver back out!
Morbid?! perhaps! But it's not like he wouldn't deserve it! ;)
