Editing Fourth Grade (section)

===Description===
Freaked out by all the demands that go along with now being in the  fourth grade, the boys enlist the help of two college kids (and Star Trek nuts) to transport them back to the third grade. To do this, the nerds rig a time machine out of Timmy's wheelchair.  The class is set to be transported back to happier times but instead of opening a time portal, it simply takes off at high speed -- with Timmy on it. After they discover Timmy's chair will explode if his speed drops below 5 mph, the kids run after Timmy to try to help him . 

It's the last straw for the boys' new teacher, Ms. Choksondik. She seeks out how to handle the students from Mr. Garrison, who now lives as a hermit in the mountains.. In the process of teaching her how to cope, he has a mystical encounter that helps him to finally accept  the fact that he's gay.

In the meantime the police manage to disarm the explosive potential of Timmy's wheelchair, which thenactually becomes a working time machine and hurtles him into the past. The class has the Star Trek nerds open another time doorway, but Ms. Choksondik prevents their departure by telling them that life is about going forward, not reliving the past.

The time portal belches out Timmy before it closes. He's obviously been all over history, but of course can't say a word about his travels. Mr. Garrison comes down from the mountains, admits to Principal Victoria that he's gay and asks for his job back. He's told the school doesn't hire gay people.
