Cletus Spuckler

Cletus Spuckler or Cletus Delroy is a "slack-jawed yokel," a stereotypical hillbilly character. As once introduced in song:

First verse:
 * Some folk'll never eat a skunk
 * and then again some folk'll,
 * like Cletus the Slack-Jawed Yokel!

Second verse:
 * Most folk'll never lose a toe
 * but then again some folk'll,
 * like Cletus the Slack-Jawed Yokel!

(complete with a follow-the-bouncing-ball).

Apperance
Generally a good-natured fellow, Cletus has been known to take advantage of others, as when he presents Marge with 300 coupons for free pretzels from her pretzel business.

Family
Cletus has 27 children: Tiffany, Heather, Cody, Dylan, Dermot, Jordan, Taylor, Brittany, Wesley, Rumor, Scout, Cassidy, Zoe, Clo, Max, Hunter, Rubella, Kendall, Caitlin, Noah, Sascha, Morgan, Kyra, Ian, Lauren, Q-bert, and Phail, as well as a wife, Brandine, who refused to wear boots to her strip club audition on the grounds that it would scuff up the stage, telling Cletus he "best take 'em back where from ya got'em." It is also implied that Cletus and Brandine are siblings, as in one episode they are parked at an auto racing event, and Brandine remarks "Why did you have to park so close to my parents?" to which Cletus responds "They's mah parents too!"

In addition, in the Season 16 episode "There's Something About Marrying", Homer (who has become ordained as a minister) is marrying Cletus and Brandine. Looking at a form, he asks "Wait a minute... are you two brother and sister?" Brandine replies, "We's all kinda things." Cletus and Brandine have a daughter named "Condolleezza Marie", who was somehow switched with a bag of sugar that Homer had been carrying around for a week.

Last Name
Cletus' last name is likely "Spuckler." At least two episodes (the first being "Sweets and Sour Marge", in which Cletus signed his name to Marge's petition to ban sugar from Springfield, and the second being "Marge vs. Singles, Seniors, Childless Couples and Teens, and Gays" in which it appears on the screen in a news report) give his name as "Spuckler" and in "The Simpsons: Hit and Run" video game, the mailbox outside his shack says "Spuckler."

Foster Parents
In the season 14 finale, when Homer and Marge were set to die, Cletus and Brandine were to become the foster parents of Bart,  Lisa and  Maggie.
