"One, two, three, four, five" is a popular English language nursery rhyme and counting-out rhyme.

Common modern versions:

One, two, three, four, five,

Once I caught a fish alive.

Six, seven, eight, nine, ten.

Then I let it go again.

Why did I let it go,

Because he bit my finger so!

Which finger did he bite?

This little finger on my right!

The rhyme is one of many counting-out rhymes. It was first recorded in "Mother Goose's Melody" around 1765. Like most versions until the late nineteenth century, it had only the first stanza, and dealt with a hare not a fish, with the words:

One, two, three, Four and five,

I caught a hare alive;

Six, seven, eight, Nine and ten,

I let him go again.
