Jez Watts' Absolute Zero is named after the fact that he owes his fiancée $16,000 and needs to pay it all back before they can get married. Whether she'll still be keen to marry him after a 50-minute show full of dirty jokes (mostly about her) remains to be seen, but he's making good progress towards reducing that debt, so there may well be a wedding soon.

The show is loosely structured in three parts. It starts with anecdotes about his younger, drug-fuelled days, a time he looks back on with rose-tinted glasses. The middle section is where the filthy gags come into play. Watts' show is advertised as being 'playfully dirty', and he doesn't hold back. His brand of gross-out humour isn't for everyone, and the audience is divided.

Finally, Watts ends the show with a long yarn about a flat-earther colleague, followed by a song about chickens taking over the world. It's very out of place and although Watts has a surprisingly nice singing voice, he could reconsider how to incorporate music into his show a bit more smoothly. Overall, this is a disjointed mishmash, ably demonstrating that Jez Watts hasn't quite decided what kind of comedian he wants to be.
