a joke that i saw in a youtube video a few years back Two markets were flying in the the sky, when suddenly Market 1 stops and says "Wait a minute, markets don't fly", to which Market 2 responds "Oh, right" before falling down to the ground. Upon landing Market 2 looks up and sees Market 1 still up above, so he shouts "Why are you still flying? Markets don't fly!", so Market 1 shouts back to Market 2 "Ah, you see my friend, i am a Supermarket!"
