We had a 1-900 number ro call to find out who won the Mr. O....otherwise we had to wait for eons !!
I believe that was on American Muscle, too: 1-900-PUMP-IRON.
That was the number used in 1991 (same episode as the one with Kevin Levrone) for fans to vote for the MuscleMania Grand Champion, the best of the 5 regional winners. It was Nick Sillette (Atlanta), Mike Francois (Chicago), Sal Princiotta (New York), Ted Lopes (Providence), and Dennis Newman (San Diego).
Francois got the most votes.
The 1992 WBF championship actually had a hotline for fans to vote for the WBF champion (1-900-454-WBF2), the proceeds from which was supposed to go to the Special Olympics.
