Tweeter Annette Thomson - aka @NettieWriter - is, as she says in her Twitter bio, a "writer, photographer and poodle wrangler".
She also suffers from depression, as have many of her family and friends over the years. And now she's decided to use the power of Twitter to help those with mental health issues.
Following the example of tweeter @JaneTravers - who collected recipes through Twitter using the hashtag #Tweettreats and published them all in a book to raise money for Médecins Sans Frontières - Thomson has undertaken a similar project.
Only she's not collecting recipes, she's collecting jokes - the best of which will be compiled in a book called Crying With Laughter. All proceeds from the sale of the book will go to the mental health charity Sane.
"I get very angry at the way society and employers still ostracise people who suffer from mental illness," Thomson tells The Huffington Post UK. "I wanted to do something to help - and thought the most effective way would be to raise money for a fabulous, caring charity which does so much to help those with mental health issues."
So whether you're a professional comic or just have a favourite gag you want to share, tweet your joke using the hashtag #TweeHee to contribute to the project. You can also find out more at the TweeHee website - and through @NettieWriter's feed.
Here are just some of the jokes that have been coming in so far...
