A Still, Small Fly lyrics

A still, small fly sits poised on a smooth, white pill
He hums old melodies heard at mum's bony breast
As he lapped the juicy, hot milk
Mum was certified TT
Derek, the fly, with a wicked smile dashes into  the air
Zooms over Heimi Goldfish in his bowl and
Pow!
Drops a busy onto the surface
Heimi Goldfish doesn’t care, he is extremely busy himself
Thanking God he took spherical trig as a child
Derek doesn't know that Heimi doesn't care
He didn’t take Yiddish for his O Levels
