Public speaking is a state of mind. Chicks performance attempt was a no go.
It's also a personality type.
Thinking that you are being witty and clever because you can pull out the same stock phrases all of the time may work in a studio (and to be honest, I think it doesn't work but obviously there are people who buy into it) but being an MC is whole different game. I mean, people make careers out of being an MC.
This is just another example of jobs for the boys.
