One of these videos was about the fake bomb prank. I myself remember watching this video back when it was still up, sometime in early/mid 2011. From what I remember, the video was about grandpa receiving a package in the mail. He opened the box to find a bomb inside, and Michael pretends to contact police on his cell phone (secretly contacting a friend of his who was in on the prank). From there, they are given instructions on how to deactivate the bomb. Michael tells Grandpa to cut one of the wires, so he gets a pair of scissors and cuts the wire as told. Michael immediately yells saying he cut the wrong wire and that the bomb would explode. Grandpa grabs the bomb and throws it out the window, before running to another room in his house with Michael. Then Michael told him it was a prank and Grandpa has a complete meltdown, and that's all I can remember. I think like 3 or 4 weeks after the video was uploaded, Michael removed it from the channel. Thankfully, for reasons I don't remember, I took a screenshot (albeit very amateur). However, Michael claims to reupload the entire prank soon in an update video 1 week following Grandpa's death in an update video, which features a clip of the prank. RIP Angry Grandpa 1950-2017, we love you AGP!
Oh thank god someone saw my thread, anyways I understand what you mean but it's considered lost until someone uploads it. If we go by what you said then it was lost for almost 7 years.
