George Lopez Arrest ... I Did to Canada, What Justin Bieber Does to America!

George Lopez says revenge is a dish best served drunk ... or at least something like that.

Lopez took the stage at Caesars Windsor Friday night in Canada -- just one day after getting arrested for public intoxication at the same hotel -- and candidly spoke about his arrest.

The comedian opened the show saying, "I just did in Windsor, what Justin Bieber does in America" ... then told the audience he took 52 shots before passing out in the bar of the hotel the night before.

One thing George makes very clear throughout his gig ... the arrest didn't cramp his style.

Eh, take that Canada!
