Vito's mispronunciations, etc, were funny last year, as they were authentic, and tended to only pop up in SM. It's all becoming rather stage managed now. Like producers have found something that was natural, cute and funny, and now want to flog it to death.
It's like on ITT when they had Nikita doing that Layton's lingo quiz - it was really cute how Nikita was picking up on Layton's turns of phrase and using them in his own speech, it was just organic. But then the show notices and tries to manage it and make a thing of it.
