我要一篇英语的课前演讲,一分钟左右的,可以是诗篇,也可以是幽默短文,

A man comes into a pub,sits down at the bar and orders a beer.The bar keeper brings him his beer.After he has drunk it,he grabs in his bag and puts a small piano on the bar,grabs in his bag and puts a small chair on the bar and grabs a third time in his bag and sits down a small man on that chair.
And the small man plays piano very well,a the most beatyful music they've ever heared.After he's finished,everyone applauds.And the bar keeper asks the man:"Where do you have it from?It's so wonderful."
And the man said:"I own an dgini-lamp.And so I got this by a wish of mine.Hey," he said to the bar keeper,"do you have a wish?You can wish you everything!"
Q:What's the main difference between intelligence and ignorance?
A:I don't know and I don't care!
