I'm going to try this again, I don't really remember much about the movie but one of the parts they show a van like with a giant hot dog on it. Also there is another part its like a construction site and I remember a part where someone take the shoot part of a cement truck and turn it so that it releases all the cement into a car, and it messes up the car. It's a romantic comedy in the early 80's. The main guy of the movie almost losses his girl to another man, she is getting married in some kind of park, and he tries to get to the park to stop the wedding, At the end of the movie the guys flies down to the park on like a paraplane, some kind of flying thing with wings, and stops his woman from marrying another man. His woman is getting married in a park or something. Im so sorry it was so long ago but I really want this movie title.

Maybe problem child 2? But it's quite a stretch. Sorry I couldn't be more help.
