 Back in 2015, I saw a grown adult on YouTube who had never seen or heard of a can opener. I was so thoroughly disgusted, I made a video about it, and here it is. Captain Sparkles on the Nerdy Nummies show this week couldn't open a can with a can opener. I mean, look at this mess. He said he hadn't done any cooking in 15 years. Opening a can is not cooking. It's not difficult. It's not a mystery. Here's how you do it. There. Open can. Teach your kids to use a damn can opener.
