Patrick F. "Pat" Kilbane (born November 5 1969) is an American comic actor. He first appeared in a 1996 episode of Seinfeld (The Bizarro Jerry), in which he played Bizarro Kramer. Kilbane appeared for several seasons on MADtv, most notibly the Spishak spokes-person. At 6' 5" (1.96 m), Kilbane is one of the tallest comedians in the entertainment world.

Best known for his three-year run on Fox's "Mad TV" (1995), Pat Kilbane made his mark on the show with outrageous physical comedy and uncanny celebrity impressions. Among his more memorable characters were Stan the Java Man, the shady Spishak spokesman, and the floppy superhero "Rubberman. Kilbane's impressions are too numerous to list, but notably his mimicry of Howard Stern (I) and Lyle Lovett fooled some viewers into believing that the stars actually appeared on the show. After the expiration of his contract with "Mad TV" (1995), Kilbane was signed to a two-year deal with Dreamworks, during which he appeared in the movies Evolution (2001) and EuroTrip (2004), and on ABC's hit show "Spin City" (1996). The deal culminated with The Pat Kilbane Show, a smart, edgy sketch comedy vehicle that Kilbane wrote and executive produced for Comedy Central. Raised in Dayton, Ohio, Kilbane earned his bachelor's degree in French from Beloit College before beginning his career as a stand-up comedian. He headlined clubs throughout the United States and was featured on Showtime's "Full Frontal Comedy" (1996) as well as A&E's "Evening at the Improv, An" (1982) and "Comedy on the Road" (1995). After moving to Los Angeles, he appeared in over a dozen national commercials, made guest appearances on "Single Guy, The" (1995) and "Arli$$" (1996), and played the role of the Anti-Kramer in the Emmy-nominated "Seinfeld" (1990) episode "Bizarro Jerry."
