I wish I could find it, but I searched with no luck. There was this great interview with Steve Wozniak, creator of the Apple II computer. In the middle of the interview, they took him to this museum and they had this old apple II there (might have been an Apple I) Anyway, he fired it up to see if it would work and the video was on the fritz. He said: "Oh yeah, those old boards did that. Do you have a soldering iron? I can fix it."
So they get him to a bench, and he has this lead spool of solder, and he loops it through his mouth and holds it with his left hand and the iron with his right, so he can let out the solder as he goes. Like it was just the most natural thing in the world. There is this billionaire causally working on the solder joint of a 40 year old computer, with solder in his mouth.
It was something else.
So Kiss it? Woz French Kissed it. (Just the solder though, not the iron.)
