The stadium that the baseball game is played in at the end of the movie is clearly Dodger Stadium, home of the L.A. Dodgers. It makes sense for them to be there because the movie's in L.A., of course. But the home team is the California Angels, who play in Anaheim, and should not be using the Dodgers' stadium.
Spoof films are just that: SPOOFS! If you say that the stadium was a slip up so was Nordberg getting shot, burned and drowned, yet, he only had a broken leg in the hospital. C'mon!
