Funny Racial Joke

A man who found himself speaking with a Nigerian accent went to a doctor with much angst having heard that there are people plagued by a fictitious condition referred to as 'Nigerianitis'.
Having mentioned his concern to the doctor and the possibility that he might have the condition the doctor retorted , 'Son , Do you find yourself smiling to yourself for no reason ? ' , for which the man replied yes. Into further inquiry about the man's worry the doctor then asked 'Do you often find yourself wearing flowery multi colored shirts' for which he also replied 'yes'. The Doctor then proclaimed with a gentle sigh 'I dont think you are suffering from Nigerianitis , you might however have a mild form of Ghana-ria'.
