Somehow I’d missed this one, though I’d seen people toss the name around (and assumed they were joking). But it seems that yes, the Legion of Super-Heroes did in fact once reject Arm Fall-Off Boy:

Legion of Super-Heroes in the 31st Century #16, out next week.

Spam subject:

this going to expolad

It’s a stock spam, and what they’re trying to say is “This is going to explode.” But doesn’t “Expo-Lad” sound like a character from the Legion of Super-Heroes?

Just imagine:

“No one wants to come to our convention! What can we do?”
“Never fear! Expo-Lad will save us!”

Update: I can’t believe I didn’t think of this earlier, but maybe ExpoLad is related to TypoLad!
