Everybody's free (Yodas advice)

Sunscreen good
No sunscreen bad
Rest of advice based on years of Jedi teaching experience, yes.
This advice I dispense now

Enjoy the power and beauty of the Force
Understand the Force you will not until you have used it
Fabulous is how you look, Fat as Jabba the Hutt you are not.
Worry not about the Dark Side.
Worrying is as effective as trying to stick C-3PO together with bubblegum
Do one thing, everyday, that would scare even Darth Maul
Yes

Floss
Waste time not at Mos Eisley
In the end hung over you will be, yes
Kind to your lightsaber be
For when it's gone, miss it you will

Dance, even if you have nowhere to do it
but your own swamp on Dagobah
Beauty magazines read you not
make you feel ugly and green they will, Yes

Just one minute you wait
What is wrong with being ugly and green I ask, hmmm?
Get to know your father
You never know if Darth Vader he will be

Live on ice planet Hoth once
Leave, before hard it makes you
Live in Naboo once
But leave before soft it makes you
Travel at lightspeed
but make sure hyperdrive works
Accept certain inalienable truths
Luke and Leia, related they are

Wookies, shed all over the furniture they will
And sound a lot like Grover on Sesame street, I do

Respect Mace Windu
Very good in Pulp Fiction he was, Yes

With your hair mess not
Or by the time you're 800
One thousand it will look
Be careful of advice and. . . Boba Fett

but trust you me on the sunscreen

Funny parody of a great song, inspired by Lau :P
