Laurie Kilmartin's father is dying from lung cancer.

And the US comedian is live-tweeting the last moments of his life in the only way she knows how: with love, wit and a big dose of humour.

Her account is at times hilarious, at other times heartbreaking as she gives her followers an insight into her dad's journey towards the end.

Kilmartin, an LA-based writer for the Conan O'Brien show Conan, told her Twitter followers on February 21 that her father's health had deteriorated.

"Dad now in hospice. I told Dad if he sees Chris Hitchens, inform him that women not being funny wasn't the only thing he was wrong about," she wrote.

Kilmartin – a finalist in the NBC reality television show Last Comic Standing – and her family have remained by her father's side in the hospice, with Kilmartin turning to Twitter to process her thoughts.

She posted a photograph of herself with her elderly father and sister and the caption: "Surrounding our Dad with love and sarcasm."

At other times the sadness seems to hit home.

Kilmartin also posted a photograph of her mother clasping her sick father's hand, captioned simply: "55 years".

Kilmartin began rapidly gathering followers after US comedian Patton Oswalt tweeted about her to his 1.6 million followers.

Some have questioned the appropriateness of Kilmartin's humour at such a sad time, including one reader who said he was trying to "figure out what's funny about ur (sic) dad dying".

Even Kilmartin has acknowledged that she is still learning. She responded to the reader on Twitter: "I'm trying to figure out what isn't."

"Guys, I'm just trying to grieve in advance, so I can relax and have fun at the funeral," she wrote.
