@Linus Yes, I'm "Bill" - When the cartoonist (Charles M. Schulz) was born, the 5 most common boys names were Robert (Bob), John, James (Jim), William (Bill) and Charles (Chuck). By the 1990s, when this comic strip appeared, more "modern" names became very popular, like the ones Charlie Brown is reading from the roster - And Robert, John, James, William, and Charles had all fallen out of the top 10. Interestingly, within the past 10 years William has again become popular and is now back in the top 5 - So no longer rare at all!
You do know that you're named after one of the major characters in this comic strip?
@Linus Here's two from 1975 that feature Linus and Snoopy - note the typewriter Snoopy is using - within a few years those would become obsolete and be replaced by personal computers running word processing software.
