Space Ghost and Superman were fighting off various enemies of their rouges gallery while going across space, with them briefly popping up on Earth to help clean up Metropolis for they were getting some much needed time together actually acting like superheroes, which moreso was because of the latter reminding the former of what he was missing. Alas they were cheered on by the masses and they returned to the top of 1 of the skyscrapers overlooking the city.
"Feels good doesn't it Tad?"
"You know Kal, it does."
"You can call me Clark, I don't mind."
"Well you can refer to me as Thaddeus; it doesn't bother me that much."
Superman and Space Ghost just had a good laugh for they decided to have a fly around the city of Metropolis after a good quick chat.
