UFC megastar Conor “Notorious” McGregor and boxing legend Floyd Mayweather recently embarked on a press conference world tour to promote their incipient cross-promotional boxing match up.

The final stop for the tour came yesterday in London, England. There, the two fighters had a final chance to talk trash and to staredown before departing for their final stretches of training.

Now, fighters and fans are providing their thoughts on the epic world tour. Among them, longtime UFC commentating veteran Joe Rogan made his reaction to the presser in a recent edition of Joe Rogan Experience.
