There's a big calculus party, and all the functions are invited. ln(x) is talking to some trig functions, when he sees his friend e^x sulking in a corner. ln(x): "What's wrong e^x?" e^x replies: "I'm so lonely!"
ln(x): "Well, you should go integrate yourself into the crowd!"
...e^x looks up and cries, "It won't make a difference!"
