This bawdy Brummie is not for the faint-hearted. Unapologetically filthy, if not downright nasty, there are few jokes too low for her vicious tongue.

Attacking Americans for being fat or heading below the belt for laughs may not be especially big or clever - but it's the savagery of the attack, and wantonness of the attitude that get the reaction.

Sometimes, that response may be a simple 'eugh' as the depths of depravity she's plunged become shockingly apparent, but then that knee-jerk reponse breaks into laughter, a primitive reflex to the fact that such shocking behaviour is, after all, only a joke. And often the gag is much better than you'd have any right to expect from such low-level subject matter - elevating her a notch or two above being a female Roy 'Chubby' Brown.

Such base humour is obviously never going to be to everyone's taste, but Murray executes it very well. You don't want to be a shrinking violet with an act like this, and she doesn't fail to deliver the attitude, timing and confidence you need to pull it off.
