Two Diet Coke Cans

I often have two diet coke cans on my desk. One is full of diet coke. The other is where I put my sunflower seed shells. I try to keep them on opposite sides of my keyboard to avoid confusion, but still, it can prove to be disastrous. Thankfully, I've never taken a sip of sunflower seed shells. I have, however (and devastatingly), ruined a perfectly good can or two of cold and refreshing diet coke. Once the shell is in, you just can't get it back out. Sad.
