I'll tell one on myself:
Had a 1466 International in the shop once. Was doing quite a bit of work to it. Needed to start it to do something (I don't recall what). One of the guys said we couldn't start it because it didn't have coolant in it.... I was like, pppppbbbtttt..... it's only going to run for a few min, it'll be fine. They, and I, forgot we had the oil cooler off. Do you know how much oil an oil pump in a DT414 will pump when it runs for about 4 seconds? A LOT!! All over the place. Shoots it out pretty far too. It was a mess.
