And he was the opening act!
Toward the end of a 10-minute standup routine at the Hyatt Regency Hotel in downtown Chicago, the 50-year-old star of "The Bernie Mac Show" joked about menopause, sexual infidelity and promiscuity, and used occasional crude language.
Fortunately, the audience heard him for the foul mouth fool that he was, and heckled him.
"It's not funny. Let's get Barack on," a man shouted from the crowd, which paid $2,300 each to support the Illinois senator.
When the obamanator came on stage, he gave a tepid, backhanded rebuke toward Mac:
"This is a family affair. By the way, I'm just messing with you, man."
The incident drew response from Obama's campaign, which criticized Mac for his choice of material.
Bus driver. Move that bus!!
