The straw that broke the camel's back

"Everything about this video is completely harmless, the man was still working and moving after this happened he was not hurt in any possible way. At around 11:30 my mom and I heard a huge sliding sound and we thought something fell off the roof due to the roofers working we didn’t think anything about it. At around 11:50 my uncle came home and said the deck was completely off the house so we went and checked the back porch and sure enough it was completely off the house. That’s when we pulled up my cameras and saw the footage of the man stacking 55 Lbs each of roof shingles, and four rows of three which were probably 12-13 rows high. Around 2,000 lbs sitting in one spot and it collapsed our deck. The ending result was a bunch of laughter and a funny video to come of it!"
