Siobhan
Siobhan is a post-op transsexual and the most senior member of the Wack Pack. She appeared on Howard's show way back in 1986 when she was still a he named Bill and had male genitalia. Since then, Siobhan has gone through multiple surgeries to finally become a woman and has the private parts to prove it. In 2006 Howard held a contest to help Siobhan lose her new found female virginity. A listener named "KDK" won the contest to be the first person to try out her newly-created private parts. Siobhan is also well known for being a squatter in a filthy, cat-infested apartment in NYC.
