This one (http://hoodie-time.livejournal.com/119369.html?thread=855881#t855881) is probably the most well-known, and it's very excellent. It spawned a couple remixes as well. Here's one:

Thank you! That was really fast. Something like "Just as easy as 123" is exactly what I was looking for!!

Excuse me, but dyslexia =/= "not smart".

You're right of course! I should have formulated two separate requests.
I hope I caused no offence.

Edit: Fixed it!

Oooh I love both of those requests, hopefully I'll be able to snatch a few I haven't read yet :)

Here's a bunch I know of:

#1.

Someday Never Comes by Gila
http://gilascave.livejournal.com/123061.html
He turned away and headed for the kitchen, with Dean still following. He glanced down at his oldest, wondering if there was something else. "Anything wrong?" he asked, knowing surely it would have first thing out of Dean's mouth if something had happened.
Dean shook his head, but was frowning slightly. John only had to wait a second before Dean said, "I gave my book report at school today."

http://melodious329.livejournal.com/9647.html

Flagstaff by nong-pradu
http://nong-pradu.livejournal.com/15796.html
One of Sam's 'greatest hits' in heaven was his two-week vacation from his family in Flagstaff. According to Dean, there were some consequences "when Dad came home" that Sam had no idea about. *Super vicious and owwy :(

Rock Salt, Iron Rounds, and Devil's Traps in Pen by yesterday4
http://yesterday4.livejournal.com/162344.html
Dean knows that you identify a spirit by looking for ectoplasm, even if he doesnt actually know what ectoplasm is. Dean can draw a Devil's Trap in pen and without a ruler, even if it is a little crooked. And Dean can be a little soldier even if he's so scared and isn't really sure what to do.

Bunnies Gone Bad! by morning sunlight

Dean tries to cope with looking after Sam, helping him with his homework, doing his own homework, and making sure they have food to eat and clothes to wear whilst also trying to fight off a chest infection.

Apparently my awesome reccing skills were too much for livejournal to handle and I need to put these in a separate comment ;)

#2.

dys · lex · i · a by 7-daze
http://7-daze.livejournal.com/3313.html

http://ht-murray.dreamwidth.org/51972.html#cutid1

This Place is Haunted by ebolacrisis
http://ebolacrisis.livejournal.com/2427.html
"I know he used to hit you.”
Dean shrugged with exaggerated casualness. “Only when I screwed up.”
“And – and then it was over, you know. We could move on. I didn’t - I was never guilty anymore afterwards. It was fair.”

Losing Control by eloise_bright
http://eloise-bright.livejournal.com/156682.html#cutid1

gone by wave obscura
http://wave-obscura.livejournal.com/2880.html
“It’s worth it to me,” Dean repeats, as if that’s supposed to explain everything. “It’s my job. Just. Let me be good at my job, Sam.”

The Wellington Fort by Rafikiven
http://rafikiven.livejournal.com/5815.html
Dad and the boys stay at Wellington, where the both of them build a fort, where Dean grows up, and where Sammy stops believing in superheros.

Aaaaaaand I'm going to stop recccing now, but feel free to check out my delicious where I've got tons more (do I read too much fanfic?... Nah that can't be it!)

Oh also, your request immediately made me think of a fic in which there is scene wherein Den is washing the dishes while John teaches Sam how to swim (and then Dean sneaks out at night to swim in order to learn faster, but John is all well it's about time you learnt) , but I don't think it's any of the ones I already linked and I can't find it on my delicious... So if anyone recognizes it that'd be awesome!

Every single time I read "Dean Reads" I start to cry. I love that story so much. Can't recommend it enough!

Wow, thank you!! I'll definitely check them out.
