The upcoming lineup has been unveiled for one of the most successful reality competition franchises, the Los Angeles Times reports, and as usual the show has gathered up its share of intriguing “types.”

Among the contestants for the fall 2012 edition of CBS’s “The Amazing Race”: a double amputee, Chippendales dancers, a former member of the metal band Megadeth, a lumberjack, twin sisters, a gay goat-farming couple and married monster truck drivers, the story reports.

“In order to keep things fresh (as if Chippendales dancers racing around the world wasn’t fresh enough), the producers are also introducing a new twist: If the team that wins the first leg of the race also wins the final leg, they will double the cash prize, taking home $2 million instead of $1 million,” the report adds.

The series’ 21st season is set to premiere Sept. 30, with Jerry Bruckheimer executive-producing. Besides doing well in the ratings, the show is a favorite of Emmy voters — winning outstanding reality competition program in eight of the past nine years, the story points out. “Top Chef” broke up the streak, winning the category in 2010.

Phil Keoghan hosts the program.
