hey, my throat is sore ! Not my fault ! squee-ed too much last evening !

I love the 'sir' too, and that means that both "Jack" and "captain" (maybe he did a Firefly marathon recently and the suspenders make him think of Mal) sound unusual, so... whatever the way he calls him, it almost always sounds kinky ! (no seriously, I see what you means with the "Jack" thing. It gives meaning to the use of the name somehow)
