[Homer re-shingles the roof. Bart is up with him.] [trying to hammer a nail]

Steady... Steady... [Homer pulls the hammer back and stabs himself in the eye] Oww!!!

[Bart laughs at him] [pulls hammer from his eye but keeping his hurt eye closed]

Why, you little--!! [strangles Bart] I'll teach you to laugh... at something... that's funny!!!

[struggles free]

You know, we are on the roof. We could have some fun.

[bitter]

What kind of fun?

... How about a dare contest?

[lightens up and opens his injured eye]

That sounds fun. I dare you to... climb the TV antenna!

[does so]

Piece of cake.

[shakes the antennae]

Earthquake!

[They both laugh. Bart is thrown off the antenna and bounces down the roof, grabbing the gutter before he can fall off.] [shakes the gutter]

Aftershock!

[They continue to laugh, until Ned Flanders notices them from his garden.]

Homer, I don't mean to be a nervous Pervis or anything, but if he falls, couldn't that make your boy a parapleg-erino?

Shut up, Flanders!

Yeah, shut up, Flanders!

Well said, boy!

[They high-five, and then Homer gets out his hammer again, readying another nail for the gutter.]

Steady... Steady... Steady... AAAAAAAAAAAAAAAAHHHH!!!!!
[Homer has fallen through the roof. Bart laughs at him again.]
