A lot of the quotes people have put down on this is the ones i laughed the most at
the one about magnus all i could do was shout "what age are you then?" i got quite a lot of worried looks from my parents

My absolute favorite in this book is the one about Magnus freezing Sebastian. "Nice, bah. He's gorgeous (gazing dreamily in Sebastian's direction). You should leave him here. I could hang hats on him and things." I laughed out loud at this one and I got rewarded by a strange look.

Who wouldn't want a gorgeous hat stand?

Right after they saw Magnus at Ragnor Fell's place.Sebastian,thinking Magnus was Fell,asks Clary about Magnus Bane,if he's much like the warlock they'd just met:
[...]The smoke was puffing out of the chimney in the shape of little dancing figures.Dancing Magnuses?She couldn't tell from here. "He's the High Warlock of Brookyln."
"Is he much like Fell?"
"Shockingly similar"

plus,I absolutely loved the 'dancing Magnuses' thing show off!I'm actually quite surprised no one posted it before me.

I think this one is in CoG
