Ha! Ha! Humble Head!
These two bright young women are clearly enjoying humiliating their local public humble head with their dirty shoes and boots. But, to be honest, the public fool is just glad of their foot company on such a cold and lonely night!
Note how the young woman having her boots kissed is deliberately making him kiss the muddiest, dirtiest part of her boot. Ha! Ha! Humble Head! What a fool you look, down amongst the muddy shoes and boots. No wonder the two girls are laughing at you! We join with them in mocking you – you kisser and licker of other people’s dirty shoes. You really are a nothing and a nobody, with your mouth full of shoedirt. Ha! Ha! What a chump! What a cluck!
