Brian Regan, known as the comedian's comedian, will be headlining four shows in Israel in late May as part of the Comedy for Koby Tour.The 59-year-old American stand up master has made his legend through off-center observational takes on daily events and childhood reminiscences, spiced with body language and facial extortions. Jerry Seinfeld described Regan as one of his “favorite, favorite comedians” and invited him to be one of the first featured guests on his online series 'Comedians in Cars Getting Coffee.'Los Angeles-based comedian Avi Liberman, who founded Comedy for Koby a decade ago and has recruited the lineups that have been performing in Israel to benefit the Koby Mandell Foundation, called Regan "the definition of stand-up genius.""When comics I have brought in the past would sometimes be concerned as to what material they should do, I would actually use Brian's name as an adjective. 'Do your most Reganesk stuff' and then they would all laugh and say, 'OK, I get it’, “ says Liberman "He is pretty much the best at what we do. No comic on earth would honestly say they are funnier than Brian."The May shows will hit four cities beginning May 26th at the Herzliya Performing Arts Center followed by performances in Chevel Modiin (Airport City), Tel Aviv and Jerusalem. Liberman will also perform along with opening act Joe Bolster.The Koby Mandell Foundation serves the needs of victims of terror and tragedy and their families and is named for the 13 year old killed in 2001 in a terror attack alongside his friend Yosef Ishran.
