I tried canned laughter with buttered peas for dinner once. The peas stayed down.

Totally agree about the canned laughter. My preference has always been UK humor, cannot understand the US so called funny shows sometimes. I guess each to his own.

If you want to try something fun, put a straw in your mouth in the way a pirate holds a knife in his mouth while climbing in movies. Sorry, best way I could think of to illustrate it. Anyway, hold a straw in your mouth that way and listen to a laugh track. There's a good chance you'll laugh uncontrollably. It's because when you hold a straw like that, you're using the same muscles you would be for laughing. This activates some of the neurons responsible for laughing and when your brain hears laughter, it's too difficult to hold it back because now you have even more laughter neurons activated.

MASH used to be shown in the UK without the canned laughter when I was a kid but all the reruns have the chuckle track added

I've always thought it weird that they say "live studio audience." A dead one wouldn't laugh. (I hope.)

I watched TBBT on youtube without the laugh track, it was horrible. That probably goes for most shows.
