well with a name like Cecil I think his parents pretty much condemned him to three types of personalities:
1 mousy shy computer programmer, wears brown polyester slacks with suspenders, blue sox and birkinstock open toed sandles, lives in mothers basement. Enjoys playing dungeons and dragons, *SPAM ALERT PLEASE REPORT POST*, star trek or star wars conventions, and combing for high school girls in chat rooms. fairly harmless
2 passive agressive, over weight, balding, virgin, in his mid 40's, in a dead end job, (toll booth operator, dishwasher, short order cook, postman, etc...) will eventually snap and go on a killing spree, or police will find a dozen or so dead bodies buried in his back yard.
3 anally retentive douche, bitter at life bc his parents named him Cecil, and all the kids used to tease him and beat him up till he pissed his pants till he turned, oh lets say 39, and the only friend he had was a turtle. Now he is pissed and out for retribution.
