One should never yell at their mother. They brought you into the world and can easily take you out of it.
The exception to the rule: Cage fighting.
Andrew Sanchez dominated Khalil Rountree in the co-main event of “The Ultimate Fighter 23 Season Finale” to win the light heavyweight tournament, and a UFC contract. It probably didn’t help Rountree that he had to tell his mother to “shut up” because he couldn’t heard his corner!
At the end of the day, still don’t yell at your mother!
