xXSniperXx seems to be a popular name... Samuel xXSniperXx Broderick... no, maybe not.
How about Roderick?
Samuel Roderick Broderick has a good ring to it, especially when said quickly by someone with a speech impediment like Jonathan Ross.
If you want something more Escapist themed, you could do what Ben Croshaw did and give yourself a middle name from a board game, such as:
Samuel Ludo Broderick.
Samuel Scrabble Broderick.
Samuel Monopoly Broderick.
Samuel Chess Broderick.
Samuel The-Game-of-Life Broderick.
Samuel Trivial-Pursuit Broderick.
Samuel Hero-Quest Broderick.
Samuel Space-Crusade Broderick.
Granted, most of those board games make you sound like a rapper, but I'm sure there's one board game that'll suit you...
