Shaquille O'Neal doesn't have to worry about running off set for a bathroom break anymore ... 'cause adult diaper brands are lining up to give him free product!!
O'Neal, 53, hilariously waddled to the restroom in the middle of an "Inside the NBA" segment on Monday ... and fans, as well as his cohosts Charles Barkley, Ernie Johnson and Kenny "The Jet" Smith, had a field day with the blooper.
GOTTA GO!
