Kel Knight

Kel comes across as an honest, respectable, reliable man who finds out he has many talents throughout the episodes.

Kel takes pride in maintaining himself, although not to Kath's extent. He has greased-down hair and wears pants which are too high for his body, often showing his socks. He exercises often, enjoying power walks and using the home gym.

Kel's main hobby is probably his job. He takes great pride in his butcher shop at Fountain Gate Shopping Centre and also loves to cook. Together with Kath, Kel loves to exercise and do aerobics. He is a Sydney Swans supporter, much to the annoyance of Kath who supports Richmond Tigers. He is somewhat sexually ambiguous and is seen as a metrosexual. During series four he wins Fountain Gate retailer of the year and starts coming home early from work and putting up posters around his workshop to show he won, which proves that Kel is extremely passionate about butchering. Kel also didn't show up to work one time after beating up Eric Bana; this is the only time Kel has been seen slacking off work.

Kel is four months younger than Kath. He was very reluctant on the day of their (first invalid) marriage. Kel had previously had four of his past girlfriends/fiancées taken away from him, feeling he was unlucky in love and became drunk on the wedding day. He has always been a gourmet butcher. In season 1, episode 2 "Gay" it is revealed Kel is bisexual, and has had past experiences with men in the Navy. It is speculated very lightly that Kel might have possibly acted again on his bisexuality again in the episode before the wedding when Kath wonders how he managed to get the carriage for the wedding from the man who offered himself to Kath for the carriage, in which Kel replies with "Let's just say I did what was necessary".

During the film Kel is seen having a fear of flying, after a session with former marriage counsellor Marion his phobia is cured.

Kel's relationship with Kath is very good. They have odd traditions including their work-out time, which includes awkward stretching and power walking. The relationship has had limited difficulties on various occasions where Kath's ex-husband Gary Poole showed up and revealed that the marriage (Kath & Kel) was invalid as he and Kath were, in fact, still married since the 1970s. Also, Kath being older than Kel has created worry for herself. Kel likes to take over Kath's duties sometimes (as seen in "Inside Out") which annoys her; as she likes to be kept busy and be in charge.

Kim Craig, Kel's step-daughter and Kath's daughter, is played by Gina Riley. From the beginning of the series, Kim had an instant dislike of Kel, due to the fact that Kath & Kim had each other all of their lives without a father/husband figure in place. Kim and Kel rarely interact, and when they do, the mood goes "off" and the scene is completely awkward, with one muttering a single word to the other and the other either walking away or trying to give out a grin. Kel is now the focus of Kath's attention which annoys Kim who likes to always be the centre of attention. Kel often tries to express his opinion of Kim to Kath, who does not always agree with what is said.

Sharon Strzelecki, played by Magda Szubanski shows respect towards Kel throughout the entire series. She is first introduced to Kel when Kath introduces the two. They don't usually talk. A mutual respect seems to exist between these characters however, with Kel having referred to Sharon as a "good stick".

Brett, Kel's step son-in-law and Kel's best man at the wedding, is played by Peter Rowsthorn. Brett is usually the one who gets informed about Kath and Kel's sexual activities.

Before Kel met Kath, he had a bad history with women. Every person he came close to marrying was always snatched away from him by longtime friend Sandy Freckle, which raised doubt to his mind before his marriage to Kath.
