Okay, so I bought the Teen Titans Lost Annual at my friendly local comics shop today, which was written in 2000 but put on the shelf for eight years because it was so damn weird. Here is the last page.
So, like, John F. Kennedy is kidnapped by some aliens who looks like the Johnny Carson-era Beatles, who need him for their war with some furry space-hippies, and replace him with a shapeshifting duplicate, and the Teen Titans come get him, and he makes peace between the space-mods and space-hippies, but while they're away the Cuban Missile Crisis happens and the JFK-duplicate gets assassinated and the real JFK decides to let the world think he's dead so he can go back into space to help the space-mods and space-hippies.
Oh, and Wonder Girl falls in love with a space-hippie named Zora but breaks up with him 'cause he has three wives already.
JFK, Hero of Space!!!
