Can I just hijack this thread for a moment to discuss the curiosity of the tank firework? Dear tank firework.. seriously? We spend our youth idolizing you. Setting up elaborate battle scenes in which we dream of the awesome destruction you'll cause after we light your wick. Only to be utterly disappointed as half of you only partially work at all, and the other half.. some odd combination of duds, non-rollers, instant explosions, and immediate self-immolations. Yet the next year, there we are in wide-eyed joy as we buy another dozen and plan this years action. It's an abusive relationship that I've now been in for over 30 years. I keep telling myself "Well they have to be better this year!". But once again, you leave me with my head hung low, and a tear in my heart. I swear.. this time I'm done with you. Until next year...
