So, Jack's uncles, my brothers Brendan and Ryan, are so patient with him, and one of their favorite things they started doing over the holidays was watching YouTube videos of excavators, monster truck crashes, garbage trucks picking up trash, etc.
Well, this particular video - about an excavator - is his absolute favorite. It's hilarious because the song played to go with it is just so funny. Be careful, you might get stuck singing it over and over in your mind - or like Jason, singing it obnoxiously out loud. ;-)
