i love emmett--in breaking dawn, he gives bella so much trouble teasing her about being a klutz and blushing all the time and then about not attacking Edward when she had the chance (on their first hunt)
oh, and the bachelor party--"let Edward out or we're coming in after him" and dancing at the reception "let me dance with my little sister. this could be my last chance to make her blush"
he has so many good one-liners in all the books
"it doesn't count until she's conscious Rose" cracked me up in NM!
He is the perfect combination of big brother and protector
