Weekly Challenge - 4 Part Post - Part 2

Alrighty fellow nerd clansmen, here is the second part to this 4 day post challenge. Read the directions below and be sure to spread the word and come back every day so we can gather an interesting conclusion.

What I Wonder?

In this post you will submit in the comment section something that you wonder like "Why is that dogs never have boogers?".

You can still go back and submit part 1 if you missed yesterday.

Make your post a complete sentence. It won't work if they are not complete sentences.
