I keep one of the kegs in my kegerator full of kombucha for my kids. This morning, one of them asked me to pour some for them. When nothing came out of the tap, I realized that the keg was clogged (this one had peaches in it so there's still some peach strings floating around). My two-year-old had been watching me, and when I started having issues, he ran over to where I keep my quick disconnects, grabbed a black one, and ran back to give it to me. 
He's a keeper.
