I wrote this limerick is it good?

[?Simply Me?]

Okay so we have to write a limerick that follows the AABBA pattern and is school appropriate. Preferably funny! This is what I have:

There once was a girl named Sue
Who had a paper due
She wasn't ready
So was quite fretty
What was there to do?

Do you like it? If not what can I do to it? Or do you have any ideas? I'm in 7th grade btw.

Thanks!
