in my driveway:
"Last one in the house is a rotten egg!"
(I'm really amazed that it has taken 3 children--almost 8 years in for that third child--for someone to hook onto that whole "last one ____ is a rotten egg" thing. My other two kids were never into it at all. I think this is the first I've heard the phrase as a parent!)
Cue the disinterested teenager:
"I don't care."
And that was answered with:
"Last one in the house is a rotten egg!" (Clearly, there's an echo in here here here...)
And followed up with:
"I'm first in the house! I'm a regular egg!"
