Are you the Real Riddler?

I love riddles! Lets see you can answer all these riddles. It's fun! They might seem hard, but they are soooooooooo easy.

Riddle One:

Your going to your imagery boyfriend's/girlfriend's house in your imagery car and you came to a railroad crossing. The sign on the other side of the tracks says "No vehicles may cross these railroad tracks". How do you spell that without any R's?

Riddle Two:

What do you call a room without walls?

Riddle Three:

Johnny's mother has 3 children. Two of them are named April and May. What is the third child's name?

Riddle Four:

What can you break with saying one word?

riddle three is johnny....as for the others....it'll require further thought

1) "That".
2) A room
3) Johnny
4) Silence

A guessed number 2, lol.

All of it's right instead of number 2. Try Again. Next time i'll give you a hint.
Come on it's easy!!

Riddle One: That
Riddle Two: Outside
Riddle Three: Johnny
Riddle Four: Silence

2 is still wrong. Think outside of the box.

A window? (haha kinda a lame answer I know... but I can't think of anything else...)

No, sorry. I'll give you a hint: spores?

A greenhouse?

No try again. Come on you can do it!

Correct! How did you cheat? Anyway, I will have more in the future.

Okay cool... I just typed in the question on google and I found the same riddle on Yahoo! Answers.

A mushroom? What?!
