If you've ever been to see a comedy movie in a theatre, with a very small audience, like one to four other people, you'll find that...they movie will not seem "All that funny." A packed house, with other people around laughing, makes the same film seem much,much funnier. I used to be a projectionist is a small theater. On shows that had a handful of people, there was very little laughter; SAME film, at a packed show, and the auditorium would echo with laughter, guffaws, and hoots. The same basic principle applies to live-audience shows like The Big Bang Theory...the studio audience is a collective, a group, many different people. Sitting at home and watching a comedy TV series with an audience of one is a good way to make the show un-funny. It's akin to getting drunk at home alone, as opposed to getting drunk at a party or nightclub. Same blood alcohol level, same drinks...one is kind of mehhhh, the other can be a rollicking great time. If you don't "get" how a collective makes things seem funnier, try telling YOURSELF some jokes...you know, sit there, alone, and deliver your funniest stories...see how much you crack yourself up! Some people apparently don't really think too much about things before posting nonsense.
