"Euuurgh! Mom! The butter has weird blue splodges in it!"
"It's ink. Remember, when Stephen exploded that pen cartridge after supper last night?"
"Euuurgh! What am I supposed to have on my toast?"
"You can't taste the blue, it's fine."
"I bet we are the only house where you have to eat blue butter. It's probably poisonous."
"Well your sister ate it and she is still alive. Have some peanut butter on your toast instead, if you don't fancy it."
"This is just not right."
