Larry passed away on 23 November, 2012, at the age of 81 after a battle with cancer, prompting an outpouring of accolades from his co-stars on the hit drama.
Linda, who played Larry's onscreen wife Sue Ellen Ewing in the series, was devastated by his death and on Monday, she asked fans to honour the legendary actor by joining her in a bizarre tribute referencing Larry's love of weed-smoking.
She asked followers to remember Larry by shouting the phrase 'gong bong' - a cannabis smoking technique designed to get the user super-high - as the sun went down.
In a post on Twitter.com on Monday, she wrote, "We all are saying 'Gong Bong' in Mr. Hagman's memory at Sunset. It would be lovely if you could join us. What fabulous memories we all have."
