"Jesus! JEEZ. Oh m' word."
Skip ahead to 1:38 for the big bang. Or don't. Waiting it out adds a particular flavour of nervous anticipation that makes the whole thing that much more exciting. I love Dad's breathless excitement at the beginning... and his flabergastedness when it blows up—literally—in his face. Also his son's "toldya so" at the end of the clip rounds out the whole rocketfail rather nicely.
