"It's Your Own Fault"
A classic.
"All right, Lisa. But as I'm leaving, I'm going to be doing this, and if you get hit, it's your own fault."
"Fine. Then I'm going to start kicking air, like this, and if a part of you should fill that air, it's YOUR own fault."
"Oh, I'd better go check on them. Now, Homer, don't you eat this pie."
"All right, Marge.
All right, pie. I'm going to start doing this, and if you get eaten, it's your own fault."
"OW! AH! Oh, my!"
"Oh, to hell with it."
