There was this massive seed drill machine called a "Maxi Cultivator" that was more complicated than a combined harvester and made in Italy, had to be pulled by a SAME (aka Lamborghini) tractor with a ground speed PTO, all sorts of "prototype" madness for a million dollar machine.
I worked for a company that was the USA side of the partnership to demonstrate and hopefully sell these machines to farmers doing the new "no-till" style planting. We had this thing ready to go, the day before some big farm day show, and the test runs broke something deep.
So this Italian master mechanic dude gets flown to the wilds of West TN overnight to fix this machine right now. Spoke no English, but he and our mechanics were able to communicate quite effectively. Sign language and profanity are universal.
He got it fixed in 4hr and the show went on; he hung around for the rest of event just in case, I think on the manufacturer's dime. I recall the bitching about the rate he got billed at later.
