Simpsons Quote, Where Is It From???

Hey, a friend of mine asked me about a Simpsons quote, but has no

reference to the episode from which it came. The scene goes, Bart and

Lisa are in the kitchen Lisa asks Bart "WHY DID YOU LIE? " Bart

responded,"I LIED BECAUSE IT WAS THE EASIEST WAY TO GET WHAT I WANTED."

TO ALL YOU SIMPSONS TRIVIA GENIUSES, WHAT EPISODE IS THIS FROM?

Hrrm, it seems so tough...WHY!!! I RUED THIS DAY!!!! NOW IT IS COME!!!! lol

Any more clues?
