"This is possibly the most shameful situation I've ever gotten myself in in my life, and I've done some pretty dumb things in my life," the Australian actor told David Letterman. "So to actually make a new number one is spectacularly stupid."
Crowe, in New York to promote a new movie, was angered by a malfunctioning phone at the Mercer Hotel at 4 a.m. Monday, so he threw it and struck a concierge in the face.
Along with a few hours in jail on an assault charge, the "Gladiator" star earned himself a new tabloid nickname: "Jerkus Maximus."
Crowe used the "Late Show" platform to apologize to his wife and to Nestor Estrada, the concierge hit under the eye by the flying phone.
