Conor McGregor should get a 1-way ticket back to Ireland after his violent bus attack -- so says George Lopez.
Like the rest of the world, George saw Conor's dolly-throwing rampage at Barclays Center last week ... and says he was shocked by the UFC mega-star's actions.
"What is that?" Lopez told TMZ Sports. "If you got that much cash, why are you throwing hand carts through the window?"
Our guy then brought up the possibility of McGregor getting a lifetime boot from the US of A, and he voted "yes" .
