I won’t pretend to know what is going on in this video, but it appears this youth hockey dad was really upset about some rough stuff that happened in his kid’s game. Then he slapped the glass in the most perfect spot he could have and it shattered completely. Reminder to youth athlete parents, your kid does not play in the NHL/NFL/NBA/MLB/PGA, etc. R-E-L-A-X.
You have to love the “way to go, Paul” though.
