Department of professional gibberish

For some reason, I've always loved professional in-jokes that I don't understand:

The safety people always tell you that if you’ve used up one extinguisher and the fire still isn’t out, to head for the door rather than reach for a second one. That’s probably good advice (although I’ve seen it disregarded), and I’d advise you to take it. Actually, I’d advise you never to have that decision to make at all, but that’s not always up to you. You may be doing nothing but adding sodium sulfate to a bunch of dichloromethane today, but who knows? The guys next door might be gearing up for Trimethylaluminum Fiesta Days. You never can tell.

Trimethyaluminum fiesta days! Don't forget to try out the sports package!
