Tom Lehrer as a child.
It took a while to get the mix right, and for a while the pigeons were able to exact revenge...

"All the world seems in tune
On a spring afternoon,
When we're poisoning pigeons in the park.
Ev'ry Sunday you'll see
My sweetheart and me,
As we poison the pigeons in the park.
When they see us coming, the birdies all try an' hide,
But they still go for peanuts when coated with cyanide.
The sun's shining bright,
Ev'rything seems all right,
When we're poisoning pigeons in the park.
We'll murder them all amid laughter and merriment.
Except for the few we take home to experiment.
My pulse will be quickenin'
With each drop of strychnine
We feed to a pigeon.
It just takes a smidgen!
To poison a pigeon in the park."
