Oooh Oooh!
Can I play?
I’m better with women’s names. How about these:
Prudence M. Knickerbocker
Hortencia N. Turnbull
Bertha Q. Wickenheiser
Velma T. Snodgrass
Novieta P. Tugglesworth
and here’s one I pulled out of my local phonebook ( I hope he’s not a reader of SDMB!)
Boris Tsvetovatty
Roderick B. Mundungus
Wadsworth W. Wellington III
Penelope S. Rippentrop
Quincy L. Mumford III
I see that Quincy was already mentioned!
Here’s a couple more women’s names, but I’ll let you come up with the last names:
Lucretia
Beatrice
OK, I think I’m done now!
I think my favorite fake name is Ema Nympton. Which if you can’t guess is Not My Name spelled backwards.
Chauncy Uppercrust
(Used in an episode of MAS*H)
Wasn’t there a Pvt. Charles Lamb used on MAS* H* as well?
Henoder Titsoff
Peter Goesinya
Ben Dover
One of my old standards is:
Throckmorton Grunthummer Wingergonger
Oh, backwards names? Here’s my favorite:
Enoz Yawawot
Mr Luxury Yacht
Actually, it’s Not Pmy Name spelled backwards.
J. Harrison Greengage III
Wilberfoce T. Grosvenor
Kingsley Frobisher
Professor Quigley Gainsborough
Sir Timothy Rhonstone Dawson IV of Wallshire. 
The Cartalk credits are always a good source. A few recent good ones:
Royal Payne-Diaz (related to Sasha Payne-Diaz)
and Hugh Lyon Sach.
My mother dated a boy named Charles Crawford Carter III when she was a young lass. It’s not ridiculous, but it’s awfully high-fallutin’.
Here is a real name for you
Fanny Strudel (she works in the Frnch office)
