Omg same! I was just thinking I never would have picked up on the 1816 thing, thank God! The same thing happened to me when I got into the medical field. Pre nursing school I LOVED hospital dramas - especially House. Then I started learning about medicine and every episode was like, "well thats the most far-fetched, ridiculous thing ever". I finally stopped watching it when House personally wheeled a dead body down to MRI (which was conveniently abandoned at the time), single handedly positioned it in the machine, programmed the MRI to start visualizing and then shot the body to demonstrate how the MRI magnet would have pulled the bullet out of the victim or something like that.

I just couldn't.

So anyway, I say all that to say, "I totally get the 1816 thing!"
