Let the Clerihewing begin!

Examples:

The enemy of Harry Potter
Was a scheming plotter.
I can't tell you what he's called; I'd be ashamed
To name "he who must not be named."

Tom Hanks
Has accounts in fifty banks.
His earnings took a jump
When he said, "People call me Forrest Gump."

If Tonya Harding played tennis
She'd be quite a menace.
We'd have to warn Monica Seles
To protect her patellas!

N'Sync
Stink.
Their music hurts my ears.
I much prefer Britney Spears.
