Another two opening themes i find myself humming often times
Super Dimensional Fortress Macross
Paranoia Agent(this ones a bit freaky but thats just consistent with the show itself)
"The accumulated filth of all their sex and murders will foam up about their waist and all the whores and politicians will look up and shout "Save us!"...
....and I'll look down and whisper "no."
