It Really Makes Me Wonder

so while I was at my lovely family get together I had some time to think about some things..
and I thought of some questions that we may never know the answers to, and decided to post them on here... to see if I am crazy or if other people think about the things I think about

Do dogs understand each other like humans do?
Do dogs see in color?
Can dogs really understand what we are saying?
Are elephants really scared of mice?
Why does everyone have dragon breath in the morning?
Why guys don't have periods?
Why guys can't get pregnant?
Do chickens have lips?
Does a bear poop in the woods?
Why do beans make you fart?
Why is it you can't get sick from cold weather but they call it a cold?
Will they ever find a cure for cancer?
Who though up all the names to put in a book that expecting parents, [or if you are me and are really bored in class] read?
Why dogs hate it when you blow in their face but love sticking their head out the window in the car?
Are Zebras black with white strpies or white with black stripes?
Can you cry under water?
Why are there handicap parking spots in front of a roller skating rink?
Why can pizza get to your house faster than an ambulance?
Why do you turn down the radio when you are driving and looking for something?
If barbie is so popular why do you have to buy all of her friends?
Why do we sing take me out to the ball game if you are already there?
Why do they call it rush hour if traffic is so slow?

There are plenty more, I just can't think of them right now.
