Drosophila, Drosophila, there's just no stopping ya
Just when I think I've seen none of you of late
And that therefore, there must be no more of you, to exterminate
You flit by me while I'm sat watching TV
Or land on my plate when I'm eating curry
Where did you come from? Why did you come in?
I only have fruit that comes in a tin
Why do you haunt me? Why won't you leave?
Do you covet the honour of being my pet peeve?
You've got to go but what will it take?
Why are you so hard to eradicate?
Depart today and I will buy you melons
Just leave me alone you bug eyed felons
