To my very dear friend, whom I call Bunny (as a nickname).  You have really inspired me and this is the least I could do for you. :)

Lyrics:

Bunny, bunny.
Oh, sorry you go by like Dawn Blush but it's me so
Bunny, bunny.
Happy birthday to you, I heard you're 24. That's getting kind of old, just kidding. (butsrsly)
I Hope your wishes come true, you're in for so much more. A life of success, no joking.
I wanna let you know that you've inspired me, made me believe in myself.
I need to make sure you know that you have helped me to get where I am now.
Happy birthday, Bunny!
Happy birthday, Bunny!
Happy Birthday to you, I know you're probably drunk.  Hanging out with your girlfriends (uhhm...all of them)
Your guitar's out of tune, so write a new song. About your love for Obelion.
I wanna let you know that you've convinced me, made me confident.
I need to make sure you know that you have helped me become who I am right now.
Happy birthday, Bunny!
Happy birthday, Bunny!
Bunny, bunny, bunny.
Hehe, sorry.
Bunny, bunny.
Have a wonderful birthday, bunny. Wub youuu!
