One of my favorite lines is in one episode ["The PTA Disbands"], when Lisa makes a perpetual motion machine and Homer comes in and says, "In this house, we obey Newton’s laws of thermodynamics." That’s a brilliant line. Also, any of Troy McClure’s — "I’m Troy McClure and you may recognize me from Alice’s Adventures Through the Windshield Glass," when he’s doing a drivers’ ed video [in "Duffless"]. I can come up with more if you give me time. Right now that’s all I can think of. I love my own episodes. It’s almost so surreal to watch them that I can’t. That was absolutely how I judged fame when I got the job of Harry Potter. The second thought after, "I’m going to play Harry Potter," was, "Maybe I’ll get to be on Simpsons one day." And I did, so I can die happy.
