Hi Mary!
Given the date, I’m reading this with the expectation that you will pull a reverse April’s Fool’s day prank and publish a serious story.
Rain poured down from the heavens, drenching the couple below. Clark looked up in desperation. “Give me a break, will you?!”
Aaah, a marriage proposal. And Lois gets zapped into amnesia.
"Who's asking? Clark?" She tugged the glasses off, exposing his face. "...Or Spiderman?"

Lois frowned a little, as though she also were confused. “I mean… it’s right, isn’t it?”
He shook his head. “Um, Lois? I’m not Spiderman.”
You’re confusing me about the date. Is it April 1st or is Clark living somewhere with Aunt May?
Lois scratched her head. “But you’ve never been seen together…”
Neither was he seen together with Batman. There are, however, pictures of Superman and Wonder Woman re-printed in Love Fortress International. Some people claim that they’re fake because Wonder Woman is much more… developed than in the photos.
”That’s because Spiderman is a fictional character, Lois.”

She studied him closely. “Batman?”
“Also no, but this wouldn’t be the first time someone thought so; don’t ask me why.”
/Points at earlier remark as well as stories by author of this ficlet/
Clark nodded. “You’ve got me, Lois. I am definitely Captain America.”
Her eyes lit up. “Really?”
“No.”
Since Season Five just started: Homelander?
”I mean you are important, but you’re also someone famous. Secretly, I mean.”
I was going to suggest Deter earlier. But to be more precise… Who got the whammy-jammy from Bad Brains from the evidence storage?
Also, he could be Satoshi Nakamoto.
JIMMY: No, he couldn’t. I mean, yeah, sure.
”What?!” Clark’s eyebrows rose. “I…Lois, I am. I’m Superman!” He unbuttoned his shirt, revealing the S underneath. “See?”
Lois shook her head. “No, that can’t be it. You’re definitely not Superman.”
This could be something done by Mxyzptlk. Mxyzptlk.

Mxyzptlk.
Clark sighed. This was going to be a much longer day than he’d hoped.
At least she’s not mad. Just crazy.
Happy belated April’s Fool’s Day!
