For some reason that I can't work out for myself, Brylcreem seems to be one of the more popular of the characters living in School Spirit. I don't particularly understand why, but for some reason a number of readers have asked for him to become more prominent, or at the very least, proclaimed him as their favourite.
It's honestly got me stumped why though.
My theory is that Brylcreem is the one that stands out the most in the strip -- he's smart, he's bespectacled, he has pale skin, he rarely kids around (and never bullies others) and, of course, he has slicked-up hair.
Personally, he's also one of my favorites in this trip, just beacuse of his name -- rarely anyone's nick-named "Brylcreem".
(No doubt the folks that make Brylcreem appreciate the plugs.)
P.S. -- I've also come across this Wikipedia article about Brylcreem (the gel). Since I'm a registered member of the Wikipedia family, I made a little addition to that article that you may be delighted in.
