I had a new player a long time ago (like '89) who was unfamiliar with serious campaigns... We made up his PC (a 1st level Mage) and I ran him through a short solo adventure (diggers in town had found an old temple with some undead, and he was delegated to check it out with the guard, being the apprentice of the only wizard in town).
He performed just fine, and got the chance to meet the local Marquis. The major domo is schooling him on what not to do when he enters the throne room, and asks him, "What is your name again?"
"Fast Eddy."
I hesitated for a second. Then I adopted the snootiest english butler accent I could, looked down my nose at him like an ostentatious major domo would, and introduced him as "Edward," drawing the name out for about five seconds.
He caught on pretty quick. He even made his official name "Edward Rapide" from that point on.
