Does prosper Roger Federer...?
In sev'ral ways does Roger err.
Of Roger, few be fonder; er-
-go (though I'm not a slanderer)
my stand's he's a philanderer.
     Still, Roger's wife calls Federer her
scrappy Happy Wanderer -- her

ur-irrev'rent metaphor for
panderer Herr Federer. 

     So, though the man's no Mel Ferrer,*

to whom I worry to refer, 

remains he Roger Federer.
