"I am a doctor"

"I am a construction engineer"
"I am a IT technician"
"Haha guys, I am a rocket scientist, lol"
"And how about you, silent one"
And then the silent one said:
``You hold no knowledge compared to me, you are nothing.''
``I am a TYPE THEORIST''

"I am a doctor, I'll be your doctor
I'm on my way, you won't come down today
Live for the right things, be with the right ones
Or they'll hold you down, they'll turn your world around"

But doctor, I am Perlgliacci.
