Oh yeah, the phaser, I had forgotten about that as well!
And yeah, its almost as if the writers of TWOK forgot that Khan was supposed to be both physically and mentally superior to regular humans.
Oh and on a side note, I was in the mess hall here in Afghanistan today for lunch and a terp walked by and his name tape said Khan. it took all I had not to jump up in front of him and yell "KHAAAAAAAAAAAN!" Of course he would of had no idea what I was talking about and I probably would have gotten a referral to mental health as well...so i didn't do it.
I don't know, i thought it was funny when I thought of it. LOL
