“Barry”
There once was a man named Obama
His daddy was black not his mamma
He won the election
Cuz of his off-white complexion
Now all of the whities are in trauma
“Rush”
There once was a man named Rush Limbaugh
He turned into a pill eating dildo
But his maid did tell
When her check didn’t swell
And off to rehab did he go
“The Reverend”
There once was a reverend named Jackson
Who walked the fine lines of attraction
His dick it did stray
To another woman they say
Now his wife gets the last satisfaction
