I love that these kind of shows wind people up so much. Don't watch it if it bugs you so much.
I'd hazard a guess that alot of people who watch this show, whether it's at home or sitting in the audience, know not to take it too seriously, and are watching it for some of the hilarity that it produces. If I'm not at Uni or not working and I'm up, I'll stick it on for a laugh. It's brainless, easy TV and makes you feel gratefuly you're not one of those ch@vvy-muppets.
