It is mentioned in this episode that Mama's 50th Junior High School Reunion is coming up. This means that Mama is most likely around 64 years of age, give or take a year.
(The family finds out about Mama's nickname)
Bubba: Grandma, I can't believe you had a bad rep. That's really cool! It's weird, but it's cool.
Mama: Oh, well now who's over here in the pink dress? Uh, Clarence I'm so glad that sex change finally took!
Vint: I knew my Mama wasn't a backseat bimbo.
Naomi: Shoot, I was startin' to get a whole new respect for her.
Bubba: Well, I still think she's cool.
(Mama sees Clayton)
Mama: It's Clayton Gibens! He's the one that got me voted most likely to succeed – with anyone!
Joanne: Everyone says I haven't changed a bit!
Mama: Oh really? Ya looked 70 back then too, huh?
Mama: Can't anybody in this family ever say anything nice?! (Looks at Naomi's food) Good Lord, don't tell me you're serving this slop to human beings!
Iola: Oh, come on Thelma, it'll give you a chance to show them how great you still look.
Mama: Well now that is true, I have kept my figure. Course, I'm not the type to gloat.
Iola: Oh, well, it wouldn't be gloating. It'd be more like giving them a personal goal they can set for themselves.
Mama: I'm telling ya, every guy in that school wanted to go out with me and most of their fathers too.
Naomi: Shame on you Mrs. Harper. All these years you've been calling me cheap when you're the original red tag special. Ha! Ha!
Mama: Shut up before I kick your butt in the bargain bin!
Bubba: The potato salad went bad.
Naomi: I can't understand what happened. It tasted perfectly fine when I put it in the car yesterday.
Mama: You left something with mayonnaise in the car since yesterday? Lord, why didn't you just feed em some rat poison with a cherry on top?
Mama: I wanna kill myself! Quick, gimme something Naomi made!
