When it was just the two big kids, before Atticus came, I used to enjoy calling them by other famous male and female pairs instead of calling them by their real names, Noah & Madeline.
'Hillary & Bill, are you guys ready for lunch?'
'Hey babe, where's Bart & Lisa?'
'Dharma...Greg, what movie do you guys want to watch to bed?'
I forgot the rest but ask Aubrey, I got quite creative.
Now I have to think up famous pairs of three!
'Yep, Leela, Bender and Fry loved that Teletubbies movie.'
