You know you have the best brother in the world when:

1. He wears underwear on his head just because you think its funny. 

2. You put yourself in time out so he doesn't have to sit alone.
3. He waits at the top of the slide and blocks all the big kids so you can get to the bottom safely. 
4. He sees you crying and comes to give you a hug. 
5.  He lets you bang on the keys even though he is playing his song.
