Hope you guys don't get put off by this one...
This was an old one I'd heard when I was a kid,
Q: "Why does the camel smile?"
A: "Because he knows the 100th name of God (father)."
Explanation: If I remember correctly, Christianity out of all the religions was the only one that referred to their God as a father (heavenly father).
My great grandfather, who would visit Spain from Mexico and also travel to Morocco, where he heard this.
Doing a search I found it again on the internet here.
I still think it's a little funny how camels always look like they're smiling. camel smiling
To this day I hear lots of Muslims can't name it, as you can see in this forum
Or this other list that has the names
Anyway, after checking those forums, I feel kind of paranoid for some reason.
