Basil Zempilas caused a little bit of a stir during the Australian Open women's final between Serena Williams and Venus Williams.
With Serena Williams heading towards her 23rd Grand Slam title - something she achieved, defeating her sister 6-4 6-4 - Zempilas wanted to make a comparison to the greatness of the number 23 in American sport.
"It's one of American sport's most famous numbers," he said.
"Michael Jackson wore 23, LeBron James wears 23, Michael Phelps (has) 23 Olympic gold medals."
Wait...who wore 23?
Zempilas mentioned the number again later in the match - and he made sure he said Michael Jordan that time.
Bit of an unforced error, Baz...
