[The complete lyrics are provided in the TISM Guide to Little Aesthetics]

They called my dad the only rabbi in jackboots
They called my mum the wife of my dad
They circumcised me at the Nuremberg rally (1)
That's how I became a semitic Nazi for life

I wanna have my gas (2) and sniff it too.
My mum always told me not to annex Poland (3)
My dad always told me not to invade Russia (4)
That's what you get for being a rebel:
Stuck in a bunker eating unleavened bread

[The Great Truckin Song version starts at this point]

I'm as popular as a Jew in Beirut
I'm responsible for millions of deaths
I decimated more than half of Europe
Kind of makes you want to boogie

1. Nuremberg was the site of massive Nazi Party rallies in 1923, 1927, 1929 and 1933-1938. They featured blaring Wagnerian overtures, stirring martial songs, banners, goose-step marches, human swastika formations, torchlight processions, bonfires and magnificent fireworks displays. Ironically, Nuremberg was also the site of the war crimes trials of 1945-46.
2. A reference to gas extermination chambers used in some Nazi concentration camps in WWII.
3. A bit of revisionism here. Germany actually annexed the Sudetenland (part of Czechoslovakia) and Austria in 1938 and invaded Poland (starting WWII) in 1939.
4. Germany invaded Russia in 1941. This is commonly regarded as Hitler's big mistake, losing him the war.
