I can't laugh at American or British stand-up comedians because of cultural differences. I understood it after laughing at Maz Jobrani, Peter Russel and now Mohammad. It is better to be culturally close to a comedian if you want to laugh at his/her jokes. I am not Arab, Persian or Indian. I am Azerbaijani and these cultures are closer to mine than western cultures. So if you dont find him funny enough, most probably you don't have enough information about the culture.
