For Superman, every zoo is a petting zoo.
Not having to sleep would be cool. Or horrible. I’m not sure. But you could get a lot more stuff done.
Those sexy skeletons.
No, Superman has to sleep for psychological reasons- in one pre-Crisis story he got a bit whacked out from going too long without sleep.
My all time favorite Superman punches.
Since Superman is not bothered by heat or cold, he saves a lot on energy bills. He only has to turn on the heat or A/C when company’s coming.
He can withstand extreme heat, which means he probably doesn’t need to sweat, at least at normal temperatures.
Goes as the same thing every damn Halloween.
There’s a JUSTICE LEAGUE comic where the Flash deduces that something must be wrong because Superman is sweating (at which point, cue the big reveal).
He never has to use a microwave to heat his coffee.
He can spill McDonald’s coffee in his lap without damage.
Settle down, now.
Traffic jam, schmaffic jam.
Doesn’t have to worry about getting run off the road when he’s riding a bike.
Probably pretty good at finding fish when he goes fishing.
Because if he had B.O., it would level planets. People would talk.
Batman?
But does being perved by x-ray vision hurt the girls? Is it like getting exposed to x-ray radiation? Did all the girls in Smallville High develop breast, butt, and crotch cancer?
I don’t know about the New 52 Supes, but both Lori Lemaris and Lois Lane pointed out, somewhat irritably, that Clark had a perfect physique simply by virtue of his powers, while they both had to work hard at it. (Lori had had her mermaid’s tail transformed into human legs at the times and was having to work out to keep herself a babe.)
I’m crashing into this thread to mention that the current New Yorker has an article on the origins of Wonder Woman — who created the character, and why. It’s a surprisingly complicated and very interesting story.
You’re welcome.
Superman fans always point to this as an awesome moment, which it kinda is, but it’s funny because he gets his ass handed to him right after this and has to be saved by Luthor.
thank you! 
Or gum disease.
Which is why the JLU finale sucks eggs. The writer (Dwayne MacDuffie?) was so busy being clever he forgot who the damn protagonists of the show were. I was actively irritated when I saw that.
