Homer: Hey, how come you never play your guitar any more?
Bart: I'll tell ya the truth, Dad. I wasn't goot at it right away, so I quit. I hope you're not mad.
Homer: [sweetly] Son, come here! Heh heh heh…
[Bart sits on Homer's knee]
Homer: Of course I'm not mad. If something's hard to do, then it's not worth doing! You just stick that guitar in the closet next to your short-wave radio, your karate outfit and your unicycle, and we'll go inside and watch TV.
Bart: What's on?
Homer: It doesn't matter.
