Well, this was a horrible thing. I turned on the grill to make pizza, went inside to get the dough ready, and when I came back out, there were many, many ants scrambling about inside the temperature gauge. Some of their comrades had already fallen, but there was no hope.
Of course, I ran inside to get my iPad (several more had died by the time I returned) because this way their deaths will not in vain. All ants, listen up! Do not make your home in grills. REPEAT: Do not make your home in grills.
