How about a post of Classic Client Quotes? My favorites being:
"You have no instinct for this business"
"______, you're a fucking idiot!"
"You're not paid to think"
“Did you take a stupid pill?”
"Can you make it a bluer blue? A lighter, more reflex-y, Navy kind of sky blue?”
“I love it! I fuckin’ love it! But we’ll have to change it.”
