I like Entry #18, very classy design. The Groucho glasses tend to be a little cliche in the humor world, so I don't know if you could find something else to use----maybe some medical symbol?
I don't know if you can manipulate the font for "Humor" at all. It's a little hard to read, but I know that's the style of that fun font. Can the letters be made a little thinner, perhaps, or mainipulated somehow so that the word becomes just a little easier to read?
I moved #18 back to a higher ranking----I showed the entries to a group of colleagues and they felt that the Groucho glasses were fine and made for a fun logo. Would you mind doing the word "Humor" in the same font you did in #22 (or a similar font, if you want to try something else), so it's more readable.
Regarding #33, thank you for showing it to me with the other font. Having seen them both now, I'm going to keep #18 ranked as the more preferable one----it does work better the original way you did it.
