Ewww.... not going to JeLeak's house.
I always thaw mine in a shot glass of water, then feed using a mini turkey baster. I take one out, put it in the shot glass, put the cubes back in the freezer.
There are many, many things I forget, but I haven't forgotten to put the cubes back. I'm much more likely to come back from the LFS and forget to put the pack in the freezer. Once we came back from the supermarket and forgot to get the groceries out of the car for a couple of hours...
