The grandiose bar mitzvah appears to be a U.S. invention to celebrate 13-year-olds' becoming adults, The Washington Post reported.
In an extreme example, body-armor maker executive David Brooks spent millions on his daughter's recent bat mitzvah atop the Rockefeller Plaza that included entertainment from 50 Cent and Aerosmith, the newspaper reported.
Pat James, whose Parties by Pat James plans about 80 New York bar mitzvahs a year, is the most sought after planner.
"Casino stuff" including poker and other wagering games are the most popular with today's teens, James said of bar mitzvah's booked years in advance.
"It can get pretty competitive among the parents," James told the newspaper. "I've had fathers say, 'I'll hire you, but only if you put on my son's bar mitzvah first.'"
