Conor McGregor laid into Floyd Mayweather during their second day of press in Toronto yesterday.
The Irishman started out by taking jabs at what Floyd wore, saying he looked "like a 12-year-old break dancer."
McGregor then took things one step further by asking Floyd, "What are you doing with a school bag on stage? You can't even f***ing read."
And of course it being in Toronto, Drake made an appearance.
