Disclaimer: I do not own Legion or the Family Guy joke.
The Carolonia Alt joke is from Family Guy. Now you understand the title. And, I did a two-for-one. Jo and Tinya.
"So, I like your outfit. Especially the brooch."
The three versions of Tinya Wazzo, one being Tinya Wazzo-Nah, were walking down the hall of Legion HQ and discussing their varying styles. The oldest Tinya, the Phantom Girl of New Earth, had short curly black hair. Tinya Nah, called Apparition, had long black hair and wore an outfit that bore a red jeweled brooch at the neck and a cape. The Tinya Wazzo of the 3Boot Earth had long black hair and an outfit similar to NE Tinya.
"Oh, thank you. No capes, you guys?" Apparition asked them.
"No, not for me." 3B Tinya said.
"I used to wear one back when I first started out as Phantom Girl. I also used to wear my hair in these silly pigtails after I changed my costume the first time." NE Tinya explained, remembering the old days, back when everything seemed so innocent. Seemed being the key word.
"You look good with short hair." 3B Tinya complimented.
"Really? I figured after the time I spent in that case in the JLE's HQ I probably look like Carol Alt." The three laughed.
...
Meanwhile, in the "real-world" apartment of world's oldest supermodel Carolonia Alt.
"Carol, come in here! They're mentioning you in a comic book!" Her equally old husband called from the living room of their tiny apartment.
"What?!" Carol screamed because of her bad hearing, sticking one of those giant horns people used to have if they had bad hearing. She didn't stick her head out from the covers.
"They're mentioning you in the Justice Legionary!"
"What?!"
"The Justice Legionary!"
"Izzat the one with the little blue munchkins?!"
"No, that's Super GreenFlash!"
"What?!"
"I pooped."
...
Now, back in our comic book world, the Jo Nah of Earth-247, likewise named Ultra Boy as were his other counterparts, came flying down the hall.
"Hey, Tinyas, any of you seen the other mes?" He asked the three Tinyas. They pointed him to the Mess Hall, and sure enough he found his older New Earth counterpart and his 3Boot counterpart seated at a table.
"So, older me, what did you wanna talk about?" 247 Jo asked as he sat down next to his older counterpart.
"Yeah, what's up?" 3B Jo asked on the other side. He just got there himself.
"Well, you guys notice with all these doubles running around it's gonna be hard to tell people apart. So I figured we should come up with a way to tell us apart. You following me, so far?" NE Jo asked them.
"Yeah." 3B Jo said.
"Sure." 247 Jo said.
"Kay, here's how we tell the difference between ourselves. I'm Big Man, he's Family Man," Jo pointed to his 247 counterpart, since he had a child with Tinya, "and you are Little Man."
"Why the sprock am I little man?" 3B Jo asked, insulted.
"Because that's what she said." 247 Jo joked, hinting at 3B Jo's indiscretions with his world's Imra, in his Legion HQ's pantry. 3B Lyle had a big mouth.
"That's not how you do it." 3B Jo explained to 247 Jo about how you do that joke.
"Now THAT's what she said." NE Jo said, smirking and caught up in the moment.
3B Jo fumed as his NE counterpart and 247 counterpart exchanged a high-five.
Well, at least my Earth didn't get wiped out by a guy in a hood or some pre-pubescent psychopath. 3B joked.
...
At the end of time
"Yet". Corrected the Time Trapper as he watched their conversation from his fortress at the end of time.
"What?!" Cried Carolonia Alt.
"Go back to bed, honey!" TT told her.
"What?!"
I have no idea where that came from.
