I was on my way home one day and I saw a penguin flew atop a tree. Incredulous, I walked up to it and asked how did you do that penguins aren’t supposed to fly and it replied whoever told you penguins can’t fly and I said the whole world knows penguins can’t fly and it said that’s what the whole world says.
As much as I was tempted to debate (finally, a chance to put my years of science education to good use!), I held myself back because I figured offending a talking penguin was not a very wise thing to do. So I resumed my way back home and as I was walking I thought to myself, why can’t I fly too?
And so I flew.
