This past Saturday in my local McDonald's the lady in line in front of me asks the girl working at the register:
"Is there egg on the Egg McMuffin?"
Honest.
You know how when we have babies, we moms put little bows in our daughter's hair and dress her in pink, so that everyone will know she's a girl? Or we dress boys in blue so it's clear they are masculine? I once remarked to my husband that our son was so masculine, "I'd know he was a boy even without any clothes."
It was probably a hormonal thing.
