"Five...maybe" has been a catchphrase on my radio program for almost 20 years.

"Big Poppa Pump" Scott Steiner interviews "Mark McGwire" (Buff Bagwell) on the 12.21.98 edition of WCW Monday Nitro at the TWA Dome in St. Louis. The entire segment is hilarious, but hits pay dirt just before the five-minute mark of the video. BIG HEAT.
