Here are the three best entries from the "write your own Joxer song" contest on the Potedeia Scroll

Joxer The Mighty,
Master Of Sheer Comedy,
He's always good for a grin,
He's so funny it's a sin,
And he has such sweet brown eyes,
Let alone his..ahem..SHOE SIZE..(LOL)
He's Joxer! He's Joxer the Mighty!

Joxer the Mighty
Quite a gentleman is he
With Fili as his sidekick
Pwaising like a lunatic
If you need a special lute
He's your man (and really cute)
And a pasta stainer to boot!
Ha HA!
He's Joxer,
Joxer the Mighty! 

Joxer the Mighty
gets some every night-y
if you're all alone & bored
he'll come save you with his **ahem** sword.

all the priestess want a sample,
in the hot tub of the Temple
(yeah, I know that doesn't quite ryhme,
I can't get it right every time)

We all know Gabby can't be straight
or else she'd want him for her mate
He's Joxer...he's Joxer the Mighty!
