So after Wendy tapes her show, she has an "after-show" posted on YouTube, where she just talks about random things and today she was talking about her stand up comedy that she's doing next week and how her rehearsals went.
She's reading some of the feedback that she received and literally goes from smiling to tears in 0.2 seconds, there's no in between. I know I shouldn't laugh but I BUSTED out laughing, as others did in the comments. See for yourself
