Sidi Mustapha's neighbours, the Abdellah's, had recently bought a camel and kept it in their backyard, right beside Mustapha's back yard. It was a problem because it kept Mustapha awake all night with its incessant rasping and belching sounds.
One night, unable to stand the noise any longer, he got out of bed and headed off to the Abdellah's to sort out the problem once and for all.
On his return to his bed, his wife asked him what he had done about the camel.
“Hah! I purchased the camel and brought it over to our back yard. Now we will see how the Abdellah's tolerate the noise!"
