What you do is take a well known saying, like a proverb, and replace one of the key words with "shoe."
For example:
A bird in the hand is worth two in the bush becomes---- A bird in the hand is worth two shoes.
Grab the bull by the horns = Grab the bull by the shoes
The pot calling the kettle black-----> The pot calling the kettle a shoe
And last for today: The pen is mightier than the sword becomes The shoe is mightier than the sword.
