There are some funny ones floating around. There are also some that make me think old looney tunes were based on real life events and not just slap stick humor. What it boils down to is there are guys running saws out there with IQ's lower than their drive link count.
There are some very funny and scary vids on the web about cutting down trees. I enjoy watching them but I also enjoy watching some informative stuff were you can also learn something. For years I have enjoyed watching Daniel Murphy's vids as a tutorial to being safe in a sometimes un safe work place. Many might not like him or his procedures but there is some excellent knowledge to be learned on some of these vids. https://www.youtube.com/channel/UCseSwqsha7yQm1oZhJcPhsw
