Tommy Tiernan (born 16 June 1969) is an Irish stand-up comedian, writer and occasional actor. His humour has been referred to as controversial though he describes his style as "based on instinct." Born in Cork, Ireland and raised in Donegal, Zambia, London and Meath, Tiernan began performing in 1992 around small-circuit comedy clubs. In 1998, he appeared in the final episode of Channel 4 series Father Ted and has occasionally acted since. He has released seven live DVDs since 2002: Live, Loose, Bovinity, Jokerman: Tommy Tiernan in America, OK Baby, Cracked: Live at Vicar Street and Crooked Man. Tiernan once held the Guinness World Record for the longest stand-up routine at thirty-six hours and fifteen minutes from 2009 to 2011. He also holds the record of the highest selling DVD sales in Ireland. Cracked and Loose both debuted at number 1 upon their release and reached four times Platinum and eight times Platinum, respectively. Jokerman: Tommy Tiernan in America reached four time Platinum status. Tiernan also holds the second highest ticket sales in Ireland, next to only U2.
