Bourne's a real audience-pleaser - but not necessarily in a good way.

She has buckets of confident energy with which to infuse a crowd, rousing the rabble by inviting them to shout responses ("Give me a Y")

But despite knowing which buttons to press, the material contains very few gags, and is merely a catalogue of the sort of filthy observational stuff peddled out countless times before - oral sex, big arses, saggy tits you know the drill. As a measure of the level, the best line involves a didgeridoo not used in its intended way.

Not big or clever.
