​The day has finally arrived and everyone is getting in their final jabs before the actual punching begins.

Floyd Mayweather, never one to quit harping on a message, repeated something on Twitter that he's been saying all week about Conor McGregor.

Mayweather has been doing ​a lot of chirping himself leading up to the fight, so it's a bit of a hypocritical statement. But that's beside the point.

In a response that has since been deleted (of course), Mayweather's most prominent former opponent, Manny Pacquiao, struck back with what should be hailed as the 'Tweet of the Century.'

Pacquiao pointing out how Mayweather has won a good deal of his fights is awesome, even if it does read a little bit like sour grapes.

Mayweather certainly won't be running on Saturday, since he insists he's going to knock McGregor out.

If Mayweather does run, however, McGregor is the rare personality who is going to chase.
