1.) Gary talking about Frankie having a great performance with a straight face. Ever (Gary did this several times).
2.) Kelly's ludicrous "owwwwwwww" moment (overall I defend her right to speak like she does but that was too much). I'll also add in her sick call. I actually think she probably legitimately WAS sick, and the voice wasn't a put on, but the mere fact that she opened herself up to those kinds of accusations makes the moment a cringeworthy one.
3.) Louis starting the whole anti-Misha mess on a LIVE show (and getting away with it since everyone focused on Tulisa)
4.) NOT Tulisa's comments about Misha, since Louis started that. Instead, lets focus on her rather disingenuous habit of giving acts advice one week, then criticizing them the next week for following it. She did this with Janet. Arguably she's done it to a certain extent with both Kitty and Marcus too. She's very into digging the knife in however she can to try and create a "space" to dethrone someone popular on another team.
