As his wife braves self-absorbed reality TV stars and other creatures in the Costa Rican wilds, Rod Blagojevich this weekend will venture into another jungle: the Second City show mocking him as a corrupt, vainglorious buffoon.

The ex-gov will take part in Saturday's performance of "Rod Blagojevich Superstar" at the Chicago Shakespeare Theatre, the company said Wednesday. Second City vice president Kelly Leonard declared himself "both excited and horrified."

It will be Blagojevich's first time seeing the four-month-old musical, although he interviewed its stars during a March fill-in stint on WLS-AM (890).

The "Superstar" run recently was extended through Aug. 9.

Proceeds from Saturday's ticket sales will benefit Gila's Club Chicago, which offers support for everyone living with cancer — men, women, teens and children.
