I am watching John Krasinski's interview and he is asked if he can speak Polish. His answer is: "I can speak Polish words that are related to food. I should learn. I've gone visited Poland and had the best time ever". What does the construction "have + V3 + V3" mean in this context? Is it gramatically correct? Never seen it before.
Or he just interrupted his thought and corrected himself by instantly replacing "gone" with "visited"?
