A sure sign...

It's cold outside. Freezing. So, I brought some hot chocolate mix to work with me. I decided to make myself a cup of it in my trusty travel mug that I usually get my coffee in. It is very similar to the one pictured below. I caught myself as I was just about to put the mug in the microwave! Does anyone see a problem with this? Maybe all that metal on the mug? Hmm. Maybe it would have short-curcuited something and cause the building to lose power and we could have all gone home? I doubt it. Most likely I would have just blown up the microwave and gotten in trouble. I think this is a sure sign that I need to go home and go back to bed.
