Given statement #2, here's my response to a question that Mo the Caller asked about a question I had posted:

"Which Mudcat Guest has a name which partly evokes a character in a superhero's Rogues' Gallery? '
Has this one been answered yet? Is it Penguin Egg?"

Yes, At least that's who I was thinking of. "The Penquin" is a Rogue in the Batman comics/movies.
