Carrie Davis (whoever that is)

I'm not very sure who she is, but she is apparently ticklish. The article mentions it twice.

There's an audio clip of her getting tickled on their show somewhere in the mainstream section.
The gag was they would tickle her to force her to say things she didn't want to say, for example saying that her favourite football team Chelsea (I think) sucks. Apparently she's a big Chelsea fan, since she held out for a while before breaking.
