For a show like that, they'll have a "hype" person working the crowd before taping starts to get everyone going so if they're asked to chant her name, there's a good chance they will because they'll be "in" to the whole experience.

I've been to a few tv tapings of sitcoms and someone always worked the crowd there - usually a stand up comic.

Failing that, they'll likely just pipe in the chants over the loudspeakers - the WWE do it all the time at their tapings for the RAW and Smackdown shows.

This is surely the most obvious trolliest, troll trolling that ever came out of troll, trolling land. TrollingMcTrollFace, anyone?
Why feed it?
The poster clearly thinks it is hilarious to make childish wind-up attempts on the thread, through what they think are 'ironic' 'p***take' comments about how Honey G is so brilliant etc. To me it looks like an unfunny attempt to position themselves as the forum's own Honey G!
Maybe we should try it out. It is so easy to do. How about this:
'Honey G has more talent in her little fingernail than Leona Lewis and Alexandra Burke put together.' See, easy.

She's brilliant and different

Just how deluded is this woman and how shameful of Simon and the others for pretending for a second that she had potential to win, she was only used by them all.
