Talking about funny logo, i think of something simple but memorable logo. So taken the idea from word skeptic, I made my logo basically from a "skeptical face", You know, when you raised your one of your eyebrow when you hear or saw a "seems legit"-thing.

So, I make the logo from a face, but with eyeglass, thick kind of eyeglass. For me it identical with something nerd. Nerdy means wierdly smart, and like to questioning things. And then i put an "skeptic eyes" behind the eyeglass. Plus one raised eyebrows.

For the finishing touch, i put a question mark, upside down. And guest what, it fit perfectly for a nose. The quesition marks represent the knowledge and curiosity.
