Inspired by beagledave and the Wu-Tang, I hope this isn’t common knowledge but it’s new to me. Please ignore if it’s been done to death, otherwise:
Take your mother’s maiden name as a last name, and the name of your first pet as a first name.
I’m " Bruiser Belland ". My wife is " Pussy Wexler " ( she’s got the best one. )
Anyone ?
Babe Neal.
Phil Herup
Lickem Ayde.
heheheh
There’s some humor nested away in that. I knew right away that it was in there somewhere, but it took me a minute to root it out.
Mine is Muffin Staples.
That’s pretty good, but a coworker of mine is “Roxy Swallow”. That gets my vote for the best.
Bunker Ringle?
That’s not funny at all.
Peaches Sczesny? The world’s first Polish Pornstar?! 
And the world’s 2nd Polish porn star:
Lucky Klementowski
That’s just stupid.
Morgaine Goldberg? A Jewish witch of Wales?
Uh no.
Mitsi King. That might not be so bad.
Celine Bonnet. Hmmmm… better than Morgaine Goldberg though… <wink>
Moppit Lane
Um, maybe if the porn’s setting was an orphanage… uh, no.
Maybe if you change it to " Moppit Upp "…
Mine would be Luna Goldstein. I sound like a a jewish hippy more than a porn star! Who would watch a video starring Luna Goldstein?
Ohhh GAWD! I’m sooo much the loser…
Using the offered criteria I’m Mutt Fullerton.
That’s not a porn star. Sounds more like Shania Twain’s husband if he was an accountant. Bleah.
And if I use that OTHER criterion (cat’s name and childhood street name) it gets even worse:
George Pinedale. Real Estate Agent to the (Porn) Stars.
Poky Cruse. Oh yeah. 
Midnight Pace
It sounds slightly risque, nothing hilarious though.
Frisky Johnson. Porn star or 1930s bankrobber? Hard to tell.
Vicious Smith. I’m a mobster, not a porn star!
