All the hosts of ABC's "Good Morning America" were given a t-shirt on March 6, during their report about the t-shirts that come in two colors, black and white.
The three-word phrase might have been the last words in his speech last Sunday, but they were McConaughney's very first words that he ever spoke as an actor in the 1993 film, "Dazed and Confused."
To commemorate the 44-year-old actor's famous phrase, fans are wearing it to express themselves and all for a good cause.
The launching of McConaughey's t-shirts come at a good time since the phrase is still in people heads after hearing him say it after accepting his Oscar.
A portion of every sale will support the "Just Keep Livin' Foundation," a non-profit organization founded by McConaughey in 2008, which implements after-school fitness and wellness programs in inner city high schools.
The Best Actor winner says:
"This is my first adventure into the fashion world … I'm enjoying it so far. I like working on the details, the design, the marketing. And I think the JKL philosophy is what makes it unique."
So far, the new t-shirts are only available at Dillard's or via phone at 1-800-345-5273.
