Back before I had kegging i had brewed a really nice Quad. Decided to bottle it one night after work. I was hungry so I fixed a quick snack while I was getting stuff ready and had two small identical sauce pans on the stove. One had my priming sugar/syrup in it. Long story short, I got all done and was cleaning up when I discovered I had primed about 48 bottles of delicious Quad with leftover water from heating hot dogs.
I built a kegerator and bought some kegs after that.
