When I was very young, my parents went on a motorcycle trip west and traveled along the Mississippi River. They brought back souvenirs for my sister and I - two little bears to go with our stuffed animal collections. Mine was named Cezil. The "ous" at the end was my young interpretation of making it sound awesome: See-zi-loo (plus, usernames back in the day couldn't be under 6 characters or something). People tend to say the "s" when they say it out loud, and since it's a made up name with a made up sound, I don't bother correcting someone else's interpretation. :) It's such a non-popular name that I usually get it at most places. It reminds me of their vacation that I didn't go on.
