Let me through some GnR at ya with this one.  "Putting Your Hoof Down" was the inspiration for this one.
Here are the lyrics and download link for the Mp3:
The mp3 is a lot better sound quality than the video for some strange reason... enjoy.
(whistle)
Shed a tear cause I wasn't sure
If you were the picky type
Angel I seeing  to your every need now
It's dinner time and we're here at home
But even now you still won't eat
There's no doubt
You were a picky eater

Little bunny, tastes this leaf
I'm sure it tastes just fine
I'll do my best to try and keep my patience
You slap the leaf and slap my face
Then you through me out the door
I'll do my best to try and keep my patience
(patience)
Mm, yeah

I stand in the square
Cause I'm looking for
Things on my list to make it right now

Sometimes I get cut in line
But I can not be assertive
But I know I
Do not want to be a bother

Then my friends they come in time
And they try to make it right
I'll try real hard and try to keep my patience
Little bunny, I've made it home
This dish should be just fine
got almost all the things that it takes
to make it, we won't fake it
cherry won't make it
but you won't take it

[whistle]
...little patience, mm yeah, mm yeah
need a little patience, yeah
just a little patience, yeah
I've been hang'n with Iron Will that's right
I trying to get up the fight
not hard to see you're bringing me down
I know you don't like
being told any how
the time has come that you better change

I ain't got time for your little game
Cause I feed you
you better eat what I feed you
oh I feed you
whoa I feed you
all this time
