Phineas: OK, Isabella, you start hammering nails, Ferb, you work with the jackhammer, and I'll fuse some metal with a blowtorch.
(Isabella walks over to a board, puts a nail in place, and gets ready to hammer it. She misses, and hits her thumb by mistake. Her eyes get teary and go bloodshot)
Isabella: AAAAHHHH!
(Next scene, Phineas finishes wrapping the bandages around Isabella's thumb)
Phineas: There, all finished.
Isabella: Thanks Phineas.
Phineas: You're welcome, and I'm sorry you got hurt.
Isabella: It's okay, accidents happen. Even though this was a painful one.
Phineas: That must've been painful by the way you screamed. Ferb's eardrums ringed.
Ferb: It was a painful exprience.
