Mad Simon says that he is really quite okay
He tells the warden that the CIA’s the one to blame
He whispers softly into one of his pillows ears
I’ll tell you something about every single person here
All the people in the back are really quite cuckoo
I hear the engine of my little friend choo-choo the train
Coming down the track he’s coming now to take me away
He’s really quite the wreck at least that’s what my doctor’s say
They tell me this each day, the needles in my brain
They start to itch again, they start to itch and…

They’re the ones you need to blame for my condition,
I’m not paranoid; I’m just very superstitious
They’re the ones you need to blame for your condition,
Yeah yeah yeah fuck the medication

Mad Simon says he's got a great joke to tell,
He says he’s Jesus and he’s going to send us all to hell
He says he had some tea with daddy just yesterday,
And daddy told him fun is over Son I’m on my way
All you sinners clear a path start digging up your graves,
The end is near but don’t you fear that’s what he always says
And if you need to find him, he’ll be hiding ‘neath his bed,
Or somewhere in the corner smothered in his feces he said
That’s what his daddy said, But daddy never came
They start to itch again, they start to itch and…

I’m Mad Simon, welcome to my mansion
Crazy people call it an asylum
Song Background
The song is about insanity and asylums in Britain. The character is named Simon because it always seemed British to me. He has a girlfriend named Jennifer ( of Jennifer's Invisible) and he's insane. More or less the words speak for themselves and his insanity goes from believing the CIA made him this way to drinking tea with God (his supposed father.) He claims he acts that way as a result of superstition not mental health. Finally, for the grand finale he claims his home is a mansion - not an asylum - and that we the crazies in the outside world are wrong about our own mental health.
And who is to say he is wrong ?
