Riddle me this


I choose you!
The rule of the game is that someone posts a riddle (it does not matter who) and then after 5 posts another person (or the same person) posts a new one. though the next the person who asked the question posts, he needs to state who is correct. Ex:
Riddler :what is red and awesome?
User: ______________________
User: ______________________
User: ______________________
User: ______________________
Random user101: ____Mario____________
Riddler : random user 101 is correct!
other Riddler : What is brown, walks until it dies, and looks like poop?

you get the point?

I'll start with an easy one:
What is a boat that never sinks?
