Where are all the cookies gone?

I woke up early this morning and dragged myself towards the door
when, my phone rang! Class was cancelled(yippee!)
and the need to break out in song rose from deep within.

What follows is the result of 13 odd years of education.

'Old mac donald had a farm, in indy-indy yaa.
and on that farm there were some peoples, in indy-indy yaa.
With a riot here, and a riot there
here-a-riot, there-a-riot, everywhere a riot.

Old mac donald had a farm, in indy-indy yaa...'

[Second verse anyone? - Post away.]
