That does not happen because Chuck Norris Roundhouse kicks the portal, causing the portal to go to Chucknorrisland instead, which then explodes because more than 1 Chuck Norris is too much Chuck Norris for the universe/multiverse/existence/whatever to handle. Chuck Norris barely flinches at the blast. You are turned corporeal from the sheer force of the blast, and Chuck Norris slams upon you with even further impunity than before (because Chuck Norris going through anything is Chuck Norris making a very big hole in it). Once done, he walks off into the sunset, I walk all over your currently corporeal body, and claim the hill.

MY HILL!!!
