well, except that one episode.
in that one, older brother Charlie strictly warns his little sister Lola never EVER to touch the rocket he spent 10 days, 3 hours and 17 minutes working on.
BR isn't crazy about this episode. He asks his sisters to warn him before the "scary parts" (so he can close his eyes). There are two: first, when Lola (predictably) breaks the rocket, and then later when Charlie discovers it and yells "LOLA!!"
He really can't stand those parts.
