In the post-DC Comics Relaunch Universe of SUPERBOY BIG GULP:
This is what the unread postcard KAL-EL sent the Bat-Boys looked like, before they fed it to ACE THE BAT HOUND.
It was the same card he'd also sent a few other peeps, the original having been mailed to The THREE Architects of the DCU's Great Change. It was with those fuckers in mind that Superman's simple, direct message
SUCK MY DICK
had been written, after all. When he'd learned of The THREE's latest intentions -- erasing his marriage to LOIS LANE after they had been together God knows how many years -- telling them to suck his super-sized Kryptonian cock just seemed to say it all.
There was just one little problem. While The THREE played dice with his identity for their new DCU, Superman's Kryptonian abilities had been put on hold. Thus, Kal-El knew he'd need BATMAN's help to keep Lois around.
Since he could no longer fly, getting to where Batman was also became something of a problem. After all, what good was knowing where to find Batman if he couldn't get to him?
Deciding he'd ask the Bat-Boys to borrow a Batmobile to go see BRUCE, Superman walked from Smallville all the way to the secret location of the Batcave.
He couldn't wait to see their little Bat-boy faces when he told them he knew where their Daddy was!
