In "Explosive Adventures" by Alexander McCall Smith, the characters Bill and Ed stand out among their companions not because of their appearance but rather due to their extravagant accessorization. Unlike the other two individuals, who appear worse for wear, Bill and Ed maintain a relatively decent look. However, their numerous large gold earrings create a distinct rattling sound with each step they take.

This detail about the earrings not only emphasizes their flamboyant personalities but also adds a unique auditory element to their presence. The contrast between their overall appearance and the striking sound of their jewelry highlights the eccentricity of these characters in the story.
