Three blind mice.
The lion and the unicorn.
My bonnie lies over the ocean.
There's a hole in the bottom of the sea.
17th century:
The unified countries required a new royal coat of arms combining England’s lion and Scotland’s unicorns.
The lion and the unicorn were fighting for the crown
The lion beat the unicorn all around the town.
Some gave them white bread, and some gave them brown;
some gave them plum cake and drummed them out of town.
