There's a Canadian Goose couple that hangs out near our job site. They're there every day and I'm guessing they're protecting their eggs.
Dave: Hey look, the ducks are back! Hi duckies! Oh the mother is so pregnant. Look at her. She's gotta give birth any day now.
Me: *snort* Is she carrying a litter?
Dave: Looks it.
Me: So ducks get pregnant now?
Dave: Uh, uh, I know they have eggs.
Me: Do the eggs grow inside of them?
Dave: I don't know. I've never really thought about it.
