Loool, it's been bugging me for ages how this song went.
The one I knew went along to nick nack paddy whack.

Upside Down
Upside Down,
i dont care if school falls down,
no more english, no more french,
no more sitting on the old school bench.

If the teacher rings the bell,
pull her t*ts and run like hell

Cant remember how the rest went though lol
