Matthew McConaughey learned from a very young age to listen to his mother.
The Gold star
appeared on Tuesday's Jimmy Kimmel Show
, where he shared that he doesn't answer to Matt, and revealed why.
"It's always been Matthew, for good reason," the 47-year-old actor explained. "I was in kindergarten -- my mom's a kindergarten teacher -- my buddy, John Griffith, says, 'Hey, Matt! Wanna go play out on the monkey bars?' I ran out and say, 'Yeah.' And all of a sudden I feel this hand on my shoulder."
That hand was his mother!
"She goes, 'Don't you ever answer to Matt again. I named you Matthew from the Bible,'" he shared. "So if anyone calls me Matt today... Mom, could be there, in any corner."
Can't really have a much better reason than that!
