It seems Irish rugby legend Brian O'Driscoll has one piece of advice for his new son, Billy.
O'Driscoll and wife Amy Huberman announced the birth of their second child yesterday.
Billy follows daughter Sadie, who is now one-and-a-half.
O'Driscoll retired from rugby earlier this year, while Huberman is currently writing a film script for an Irish production company.
But today, he tweeted this gem of wisdom for his son:
Son, if I can give u one piece of advice, never look a gift horse in the mouth! pic.twitter.com/6HL4S08ktZ
