The worst work related air conditioning I had to deal with was at a small shop in Boston. It was a giant 4 foot wide ancient window unit. It sounded like a truck engine. Its constant vibrations made a low pulsing sound that was the exact frequency of my skull. I would sometimes get a sort of motion sickness from it and turned it off when ever I was alone.
To do list:
1. Shave cat
2. Repair cracks in Kangaroo holding tank
3. Preorder The Book of Biff #4
4. Return box of stale Banana Breakers cereal
