Sibling Rivalry Enthusiast Mugs

"I hope you kept the box it came in."

'That's one thing about my sister - she's not fussy who she bites.'

'Danae is outside unscrupulously taking advantage of gullible people...'

"Hey! That's my little brother! Only I get to bully him."

The noise from the basement was probably nothing – but if it was, she was a sacrifice her older brothers were willing to make.

"When I suggested playing football with your baby brother..."

"Oh, yeah - I bet you haven't even got a big brother!"

"Stop trying to get your younger brother in trouble! Nobody likes a rattletale."

"Dad! Some nosy little pain in the butt has been in my room snooping around again."

Things that don't last 2 seconds...the idea that your l'il sis might actually be good at something.

"She was right about something...and I was wrong about something."

'Cut it out little brother, and remember, we live in a matriarchal society: One day, I'll be in charge!'

'I'm looking forward to when he's 5 years old so I can boss him around.'

Skinny sour-faced twins scowling at each other.

'Well, I'm sure not going to be the first one out!'

'He has my Mom's eyes and my Dad's nose, and yesterday he ate MY crayons!'

'Stop crying or Mom will think we're not having fun!'

Little Brother for sale: 'I don't care what he did!'

'So, it's equal.'

'Don't get too used to being the youngest, little brother: It won't last...'

Why can't you ever achieve anything like your brother?

"..Just bring me anything that'll scare my little sister"

'Well, I hope you're satisfied -- I turned down a chance to trade him for a brand new dollhouse!'

'The only reason I take him with me wherever I go, is because the thought of kissing him goodbye makes me feel sick!'

"Jonathan Scott Henshaw! You'd better not have your little brother in that trash bag...again!"

Technically, no, dear, your brother isn't plagiarizing you. ABC. ABC.

Hey, I was gonna eat right there! Mom!!

Why are you stinging yourself? Why are you stinging yourself? Scorpion older brothers are the worst.

Polygamists' Picnic

'I am so proud: My kids are finally fighting all the time!'

"He's my smart-aleck twin."

"Good work Tim, you snatch it all: none of this sharing with your brother nonsense..."

"I'm an oldest child trapped in the body of a middle child."

"At home there's a fish, a cat, a dog, me, and a big sister."

It's my biggest project - a database of all my sister's boyfriends.
