1. Ditto can get with anyone. 
2. Professor Oak is the best professor.

No matter how much you set a grass pokemon on fire. It will not die!.... Just faint.

life is worth living knowing that another pokemon game will come out

3. You don't need to go to school to get lots of money.

When you want to get serious about something, always turn your hat around backwards.

Professor Oak came when he heard you had beaten the Elite Four.
 

Slavery is ok, as long as you make them fight other slaves for cool badges.

Animal Cruelty is awesome.

everybody wants to be the best trainer in the world, but most just stand still and assault passerby.

To be a respected Gym Leader, you must use one Pokemon type and then act surprised when someone defeats you by exploiting that type's weakness.

Life, thats what Pokemon taught me. 
   
And this,
@Getz:

 When you want to get serious about something, always turn your hat around backwards.    

never let your mother manage your money because she'll waste it for crap

4.  Always use Quick Balls.

5. Gotta catch 'em all, gotta catch 'em aa-aa-ll, Pokemon!

6. Pokemon cannot die, even after being burned for 5 straight turns, cut, or electrocuted. Or all three.
7. Did your Pokemon faint? Nurse Joy can heal them in an instant.

8. A small ball can fit anything

9. Legendary Pokemon are always a pain to catch.

10. you can carry around a full sized bike in your backpack.  
 
(i died when i heard that bike riding music again >.>) 

11. You always start out as a new trainer in the first town of a certain region.
12. You will always have a rival itching to battle you in certain places.
13. Your rival's starter Pokemon will always have the type advantage against yours.
14. Any organization with the word 'Team' on it is usually up to no good.

11. The only asshole in the world, is the second person you can name.

My magic 8ball suddenly aint worth shit...

their names, engraved into my mind. D:

12. Small towns are apparently terrorized by pokemon and the only way you can ever leave is if someone happens to gift you a pokemon.
13. Pokemon have Universal Health Care and we see where that lead that economy, gladiatorial slavery.

Kill everything with fire. If it isn't dead, you didn't use enough fire. Light it on fire again.

14. Random fishermen will give you fishing rods for absolutely nothing.

Organized criminals believe that "Kids these days are loaded!"

Pokemon can only fly to Pokecenters they've already been to.
 
Tail Whipping will lower defense, self inflicted Amnesia will increase "special defense" but SPLASHING DOES NOTHING.

14/15/16/17/whatever number: It's super effective.

no matter how many times you think you caught them all, they'll keep inventing new ones

Kids should be allouded to bet in casinos

You cannot run without shoes on.

We can prevent deforestation by passing trought a door every time we cut a tree.

How to be  ♪THE VERY BEST, LIKE NO ONE EVER WAS ♪.  Obviously.

Being "immobilized" by love, might be the worst thing ever.

Everyone has a rival named " JERKFAC" because the names of rivals can only be 7 characters long.

That age 10 is a good time to be emancipated.
 
@skywave: The song is in my head now. Thanks.

Never buy Magicarp from shady salesmen, they just want your money.

Not surprisingly, blowing yourself up in a fight is relatively useless. (Self Destruct)

The quickest way to "Catch em' all" is not to have lots of friends with the game, but to have 2 handhelds and 2 copies of the game.

Nurse Joy and her clones are really sisters (yeah right)

Pokemon Centre nurses want your pokemon to get hurt so they will see you again soon.

You are a massive bitch who always mugs people for their money after kicking their ass.

You can't climb over hills, despite how small the they look. You have to find another path.

You can catch any Pokémon with a catch rate above 47.8125 if you put it to sleep, send out an opposite-gendered Pokémon and then throw a Love Ball.

It's fine if you never say anything, everyone else will just assume you did.

Shorts are comfy and easy to wear.

A ten year old can save the world with a couple of red and white balls and running shoes.

Thunder is a force to be reckoned with 0.o

You cannot run until you get yourself a pair of running shoes.
