Nobody knows, nobody knows
Where did that naughty little flea go?
Nobody knows, nobody knows
Where did that naughty little flea go?
Nobody, knows, nobody knows
There was a naughty little flea
Nobody knows, nobody knows
It crawled up on the doggy's knee
Nobody knows, nobody knows
Where did the naughty little flea go?
Nobody knows, nobody knows
The flea went up and the flea went down
Nobody knows, nobody knows
Upon his face there was a frown
Nobody knows, nobody knows
For he had found a little nest
Where did he go, nobody knows
Where he could get some food and rest
Where did he go, nobody knows
Where did the naughty little flea go?
Where did he go, nobody knows
Where did he go?
Nobody knows
