Sirius: We… Kidnapped you.

Regulus: What-Why?

Sirius: Because your parents can’t take care of you.

Regulus: Mayb-

Sirius: After this moment I’m your Dadfoot…

Sirius: *Points to Remus*

[Ravenclaw leaves]

Draco: it looks good everyday.

Harry: …

Harry: You make flirting very hard, you know?

Draco: You make me very hard.

Draco: *winks*

Slytherin: You got really cringy there for a second.

Slytherin: The line is slim man.

Malfoy’s eyes are grey

‘ ‘Take it,’ he said, and he thrust the sack into George’s hands. ‘What?’ said Fred, looking flabbergasted. ‘Take it,’ Harry repeated firmly. ‘I don’t want it.’ ‘You’re mental,’ said George, trying to push it back at Harry. ‘No, I’m not,’ said Harry. ‘You take it, and get inventing. It’s for the joke-shop.’ ‘He is mental,’ Fred said, in an almost awed voice. … ‘Harry – thanks,’ George muttered, while Fred nodded fervently at his side’

It’s why they agreed to his request Ron get some new dress robes out of it. They’re clever not just funny ‘they always get really good marks’ but as OP says they’re not as good as Percy, Bill or Charlie. They helped Ron get him out of the Dursleys:

‘But you can’t magic me out either –’ ‘We don’t need to,’ said Ron, jerking his head towards the front seats and grinning. ‘You forget who I’ve got with me.’

They get him into Hogsmede , they (unknowingly) helped the trio break into Umbridge’s ministry office. They liked Harry for himself 

‘This is all your fault,’ George said angrily to Wood. ’“Get the Snitch or die trying” – what a stupid thing to tell him!‘’

And cheered him up when things went wrong, such as Harry being accused of being the Heir of Slytherin

‘They went out of their way to march ahead of Harry down the corridors, shouting, ‘Make way for the heir of Slytherin, seriously evil wizard coming through …’ Percy was deeply disapproving of this behaviour. ‘It is not a laughing matter,’ he said coldly. ‘Oh, get out of the way, Percy,’ said Fred, ‘Harry’s in a hurry.’ ‘Yeah, he’s nipping off to the Chamber of Secrets for a cup of tea with his fanged servant,’ said George, chortling ‘

Or when Ron and Hermione were made Prefects and Harry felt left out:

‘Yeah,’ said Fred slowly. ‘Yeah, you’ve caused too much trouble, mate. Well, at least one of you’s got their priorities right.’ He strode over to Harry and clapped him on the back while giving Ron a scathing look.

They tricked Dudley because they know how crappy Harry’s home is: 

‘We didn’t give it to him because he was a Muggle!’ said Fred indignantly. ‘No, we gave it to him because he’s a great bullying git,’ said George

And of course:

'Give her hell from us, Peeves.’ And Peeves, who Harry had never seen take an order from a student before, swept his belled hat from his head and sprang to a salute as Fred and George wheeled about to tumultuous applause from the students below and sped out of the open front doors into the glorious sunset. 

Harry frequently heard students saying things like, 'Honestly, some days I just feel like jumping on my broom and leaving this place,’ or else, 'One more lesson like that and I might just do a Weasley.’

at eleven, was described by his teachers as ‘bright’

at the same age, according to the Sorting Hat: “Not a bad mind, either. There’s talent, oh my goodness, yes” and “You could be great, you know, it’s all here in your head”

mastered the challenging Patronus Charm at thirteen and proceeded to teach it at fifteen

resisted the Imperius Curse at fourteen and soon learned to throw it off completely, even when cast by the incredibly powerful Voldemort

also at fourteen, learned to cast a powerful Accio Charm

at fifteen, was training other students

at the same age, under extreme stress, tested as ‘exceeds expectations’ or ‘outstanding’ in every subject that required actual magic (including the dreaded Potions)

same age, cast a briefly effective Cruciatus Curse

at sixteen, became a star Potions student simply by following superior instructions

at seventeen, successfully cast the Imperius Curse on his first try, and used it repeatedly

at the same age, cast a successful Cruciatus Curse

He was able to immediately connect the dots between the package that Hagrid retrieved from Gringotts to the break in based on a news article and Hagrid’s reactions.

He was the one who figured out the motive of Quirrell when he played cards with Hagrid betting a dragon’s egg.

He figured out that it was Myrtle who died when the Chamber of Secrets was opened before and seemed to be the only one who was smart enough to actually ask her about her death.

He figured out that it was Lucius Malfoy who gave Ginny Tom Riddle’s diary (with subtle clues from Dobby) and used it to outsmart Malfoy into freeing Dobby.

He knew that Draco Malfoy was up to something (even though Ron and Hermione didn’t believe it) their 6th year. He also figured out Malfoy succeeded when Trelawney told him she heard a male voice whooping in the RoR.

He was the one who figured out that there was a horcrux inside Bellatrix’s vault judging only by her reactions to their possession of the Gryffindor’s Sword.

He figured out the connections of the Peverells, the cloak, the ring (and the snitch by extension) and the elder wand to the Deathly Hallows. He even figured out that it was Dumbledore who owned it and that ownership was passed on the Draco Malfoy and, eventually, to Harry himself.
