Since someone posted on FB that the first episode aired this day 33 years ago. I’m guessing that in CS you can start a dedicated thread. If you were to ask at GQ, you’ll have to start a new thread for every questionable scene. So, what particular move by Mac just wouldn’t work in the real world?
The first that comes to mind is fixing a perforated radiator by cracking several fresh eggs into the filler mouth. He said it will work, assuming the leaks aren’t too big. My take is that the cooked eggs will just clog the radiator and foul the engine.
Are you talking about in the original series or the reboot? I just saw the latest episode of the reboot and there was one bit where Mac does something to a walkie-talkie (or some other kind of radio) and the walkie-talkie makes a sustained high dB squeal which causes the bad guys to stop their attack. (At least I don’t think I dreamed that event in the episode.)
There was one where he started a fire from about 20 feet away by using the lens from a pair of binoculars to focus sunlight. In order for focused sunlight to start a fire, the size of the optics needs to be at least comparable to the distance away.
It was probably season 1, but I don’t remember the exact episode number. IIRC, he was hiding behind some bush or tall grass in a field, with a youngster he had met in that episode, with the baddies some distance away.
But he killed a lot of people during the show run, some actively, some passively (manipulated one baddie to shoot the other). He outright murdered Tom Strickler.
And he was not adverse to guns - he had more guns than your average Arizonan.
I don’t recall the set-up, but he was standing by a table with C4 on it and photography equipment. He and another were surrounded by baddies. He stuck the plug from a camera flash into a block of C-4, activated the flash timer, and when the timer went off it triggered the C-4 because, well, electricity sets off C-4.
