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,大家帮忙啊!

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!
