So, I was out earlier and was in one of those semi-bored states where strange ideas like this one come into your mind. :huh:
Basically, this was my idea

- imagine that the gang of seven where to go into the modern world (well, in the case of dinosaurs, pseudo-modern) and try to get themselves into decent jobs. What professions do they choose? Why, teaching!!

:
OK, its a little bit quirky (product of my mind) but here I shall analyse what the main characters would teach if they had the opportunity - it would certainly be interesting to have these subjects/classes taught by them. Feel free to add your own ideas and thoughts if you have the same weird frame of mind I do.
Littlefoot - History. He's a longneck, and, let's face it - even though its more in the realms of myths and legends, the longneck's alleged history of saving the Bright Circle and the LOOOOOOOOOOOOOOONE dinosaur is rather well-covered in the series. There's no limit to what Littlefoot could teach eager young minds - you saw he was like at the end of the sixth film...
Cera - Physical Education. Cera would refuse to teach anything generic, and, in her eyes, dull. She has a typical tough-girl approach to anything, and you can imagine her slave-driving people or dinosaurs to do all sorts of things...I mean, who hasn't though Cera would look complete in a sports jacket with a whistle round her neck? Er, probably most people actually...
Ducky - Drama. Ducky's one of those eager and playful types, especially in pretend play - teaching professional Drama isn't that much of a stretch, right? Says the former GCSE Drama student...
Ah, well, be honest, she would do well in Drama, yep yep yep...and due to her love for singing, she could probably do Music as well.
Petrie - Geography. I was originally going to put him down for English as an intended joke, but I think I need to give him his due.

Why geography? Well, Petrie himself explained a useful tool of the anatomy of flyers back in the seventh movie - fly up high and see things others could not see. He could probably draw us a map of the Great Valley if he wanted to, and he certainly knows his way around places.
Spike - Product Design. Spike is the silent strongman of the group. Whenever something needs moving or pushing, he's always called up to the job. Its certainly a profession he could pass onto the next generation - non-verbally of course. Alternatively, Spike could do Food Technology. He could introduce his students to a whole array of Great Valley flora and how best to eat it, which he'd then do all himself. Or maybe Art - the drawing in the dirt he did of Ducky in the seventh movie was better than I could of done. He's a dinosaur of many talents...
Chomper - Modern Foreign Languages. Well, its obvious isn't it? This lad's bilingual, being fluent in both sharptooth or leaf-eater. He could just as easily teach sharpteeth leaf-eater and leaf-eaters sharptooth. It might help humans to understand what dinosaurs are saying too. Chomper could possibly also teach Food Technology - this time slightly more meaty...
Ruby - Philosophy. "Hello, my students, my students, hello!" It could have come straight from Socrates...seriously, having her as a philosophy teacher would be brilliant - you can learn things from her perspective and you end up with a new school of thought. Possibly like the strange one that possessed me to do this in the first place.
