A few summers ago, I was brewing an all-grain Summer Ale. My system is all gravity. My sparge water is in a cooler on a tall ladder. My mash tun is on another ladder and my collection bucket is on the ground. My boil kettle is on the burner near by. So, I was done running my sparge water. At this time, I collected about 3 gallons and I needed about 3 more gallons of wort. I asked my self why I wasn't collecting my runnings directly into the kettle. I decided to move my mash tun in order to do that. I picked up my mash tun and then dropped it. (When it fell, time slowed down). I had grain and wort all over my garage floor. I decided to head to my LHBS and pick up some DME to make up the difference. When I got there, he was closed, so I left. Fortunately, the owner saw me and texted me. So he did sell me some DME and I finished with a descent beer.
