The comedienne Kathy Griffin started out her career with an improv comedy troupe and performed as a stand-up artist at various clubs before she hit it big. This Emmy Award-winning television personality has also appeared on TV with roles on Seinfeld and Suddenly Susan. Her show Kathy Griffin: My Life on the D-List has won her two Emmy Awards as executive producer. Griffin's brand of humor, which focuses on mocking celebrities (and sometimes herself), is often controversial but always hilarious.
