Happy birthday to my brother-in-law!
I think before you agreed to this video you said, "Don't show this to anyone." But I can't keep all the awesomeness to myself and since this was awhile ago, the terms of that verbal agreement have expired. Also, it's possible no one will read this. So, happy birthday. We would be impressed with you even if you couldn't make a knot in a rope with no hands.
And I love the cheering section at the end!
