Superman #181, p.16

APRIL FOOLS!
Superman and Bizarro have switched bodies, and now Bizarro is pretty much revealing Superman's secret identity. As Clark Kent, Bizarro is flying around the city, and going one on one with the horrible monster Bizarro, in actuality Superman.

'Clark Kent,' Bizarro: "ME SO HAPPY TO SEE YOU, ME BAKE YOU A KNUCKLE CAKE!" WHAM as he cracks 'Bizarro,' Superman across the face with little damage.

'Bizarro,' Superman: "Believe it or not, this is going to hurt ME a lot more than it does you." And he follows up with a monster hay-maker BAM towards the ground, CHOOM through the ground. He continues, "Amazing. Bizarro MAY ACTUALLY be STRONGER than I am-- but because of the way his brain functions--
--or DOESN'T function--
--he can't access his power like I could!" as 'Clark Kent' Bizarro continues to CHOOM, CHOOM, CHOOM through the rest of the world

And now for the true comedic break,'Clark Kent' Bizarro head cracks through the surface on the other side of the planet. A Chinese man, in traditional dress see this and says: "Yankee GO HOME!"
And 'Clark Kent' Bizarro responds, without skipping a beat:"ME YANKEES FAN! Me NO METS FAN!"
