Destroyed House Of Cards

''Maaaan, we were working on that Jenga tower for three hours, then you  came along and ruined everything. Nice one.''

The delicate structure, likely a house of cards, that only exists so then some disturbance (noise, vibrations, explosions, etc.) can knock it over. This is obviously Played For Laughs, but it's a pain for anyone who worked on it as they helplessly stand in place and watch as their work goes crashing down before them. Sometimes the House Of Cards doesn't immediately get KO'd and gets its builder's and our expectations. Shortly after, the house either does fall down or is KO'd by something else.
