The latest season of ABC's reality show "Dancing With The Stars" has announced its celebrity cast, and the best way to describe them is, er, uh, well, OLD.

Led by everybody's favorite stoner, 76-year-old Tommy Chong, and 73-year-old fashion icon Betsey Johnson, the cast this season is the show's oldest yet, proving you're never too old to rock and roll, or samba.

ABC made sure not to mention anyone's age in its pre-show publicity, but it was recently revealed that the show is most popular with viewers over 50 years old, so why not give the people what they want?

In addition to the two elder cast members, season 19's celebrities draw heavy from the nostalgia of the '80s.

Alfonso Ribiero, who was Will Smith's sidekick on the late '80s TV series, "The Fresh Prince of Bel Air" will be reprising "The Carlton Dance" at some point this season, and Lea Thompson, Michael J. Fox's love interest in 1984's "Back To The Future", will also be competing for the coveted (?) Mirror Ball Trophy.

Jonathan Bennett from the movie "Mean Girls", former MMA fighter Randy Couture, NASCAR racer Michael Waltrip, PBS talk host Tavis Smiley and former "General Hospital" hunk Antonio Sabato, Jr. round out the men in this year's competition.

Attempting to draw in the younger viewers will be YouTube beauty guru, 19 year old Bethany Mota, 25 year old Janel Parrish from "Pretty Little Liars", and 17 year old Sadie Robertson of the "Duck Dynasty" Robertson clan.

The women competing will be rounded out by Olympic sprinter and bobsledder Lolo Jones. 

But all eyes will be on the two oldest contestants, who have long bucked "acting their age". Chong has long been outspoken for the legalization of marijuana, and was already 36 when Cheech and Chong hit their counterculture prime in the early '70s.

Johnson refuses to "act her age", often dressing like a 15 year old, and demonstrating an incredible amount of energy.

The two elderly competitors would be hard pressed to top Jerry Springer's dismal performance in season three, which was recently named one of the worst ever.

Actress Cloris Leachman was the oldest to ever compete on the show in season seven, when she was 82. The oldest winner was Donny Osmond, who was 51 when he won in 2010.

This season's competitors has the oldest average age, even with the two teen contestants.

Julianne Hough will return to the show as a judge this season, joining Carrie Ann inaba, Len Goodman and Bruno Tolioni.

The show premieres its 19th season with a two hour episode on September 15 at 8:00 pm, late enough to be past the early bird buffet, but early enough to beat the oldsters to bed.
