Question: If the bus driver saw Dana choking Roy on the bus, why didn't she say or do anything about it? Also, if Roy got in trouble for breaking Dana's nose, why didn't Dana himself get in trouble for choking Roy?
Answer: A straightforward answer is because these events happened in the context of a movie and the writer simply did not have the bus driver respond or Dana get in trouble. Only the writer could tell you why. If these events happened in the real world, there are several possible answers. The bus driver's job description may not have a provision to discipline students. Her primary duty is driving the bus in a safe manner to get the kids home safely. A driver must watch the road and traffic, not passengers. Her quick glance in the rear view mirror would not enable her to see all that transpired. To take action would involve stopping the bus and getting off schedule; the kids would get home late and their parents would be worried waiting for the bus. Maybe she just didn't want to get involved. She could get injured if she tried to intervene. Bus drivers might get fired if they hurt a student even when breaking up a fight. She may have thought the kids need to stand up for themselves.
Why didn't the bully get in trouble? Maybe because the adults/ school officials thought the broken nose was enough punishment for his behavior. Maybe the bully is a persistent problem and trying to discipline him would only make matters worse. Maybe his parents are just as bad or worse and the school didn't want to deal with them. Maybe no-one reported that the bully started it and was choking Roy because they were afraid of him and didn't want him to retaliate. The bully looked like the victim, not offender. Maybe others thought the bully's home situation was awful and he already had a difficult life and a lot of stress. Maybe the bully has a psychiatric disorder and/or takes medication that increases his aggression. Maybe the adults also think the kids need to work out their differences amongst themselves. Maybe the bully is already under the supervision of the juvenile probation office and - one more offense - would be certified to the adult court and get even worse.
Question: Was the birth scene real? It seemed completely real, and the woman appeared to actually be pregnant earlier in the film.
Chosen answer: No, it wasn't real. Good make-up and acting, that's all.
Answer: In the world of "make believe", they used "movie magic" to zap the RV out of the water and on to dry land - with no mechanical issues resulting from being submerged. In the real world, someone called a tow truck - perhaps AAA - and the RV was pulled out of the water and it suffered water damage and needed some repairs. This movie was presented as being "real life." Bob left on a bicycle to "try to find help." Near the end of the movie, Carl said that the RV "spent two days under water and they had to fish it out." He didn't say who "they" were. A fishing pole would not be strong enough to reel in a large RV, so I think it is safe to conclude that a tow truck was used to pull the RV out of the lake.

It should be noted that "fish it out" is a common phrase to mean pull or take out, especially after searching. When people use the term, they're never taking about using a fishing pole. But often when people post questions like this, they're asking for an in-film explanation in case they missed (or didn't understand) something. If no in-film explanation was given, a reasonable speculation can be given. You don't need to remind people the movie is a movie. If the in/film explanation is uncharacteristic to real life, then one can point out that in real life it wouldn't happen that way.

It was meant to be ironic.

There was no irony, but this isn't the forum for irony anyways.

I guess I failed miserably... but wasn't the original question rhetorical?
