@Soossie The joke is the discovery that some Americans are unaware that 1,2,3,4,5,6,7,8,9,0 are Arabic numerals. Another example of the silliness of bigotry. (Not the OP, it was sarcasm)
Lol..... I was going to mention that too... and did you know that persian and Arabic have the same alphabet?? Only Persian has 5 more letters than Arabic.....
And did you know that in most Iranian schools the students learn Persian, English, Arabic, and French??
