There is a place in Africa where Muslims celebrate the moment when Abraham almost sacrificed his son. Each Muslim male in the area celebrates this event by sacrificing one male goat. The goat is killed, gutted and cleaned, and prepared for cooking.
Every part of the goat is used, including its balls. These are given to the children, who play with them by filling them with air and squeezing them to create fart noises.
I swear this is what they do with the goat’s junk. If you don’t believe me, then take a look at the documentary Michael Palin: Sahara. The images below were taken from this documentary.
