My favorite is
#99.
I love the funkiness of the fonts. I really like the subtle way you included the smile into the logo. (Several other people made a huge smile. Yuck.)
I love this look. But here's a little more input: EVERY use of the logo will include a different last word (ex.: Diabetes, Alzheimer's, Love, Heart Disease, etc.) How do you see that LAST word fitting into your logo? I would love to see the last word in the same treatment as the word "Funny."
