R-rated conversations with 4-year-olds

I laughed hysterically today at the following conversation I had with Cobb, and I needed to share it with some grown-ups:

Cobb: Andy and me and dad are boys. You are a girl. 

Me: That's right! I'm a girl! (He's never really understood boys/girls difference before)

Cobb: You have giants in your pants

Me: Giants?

Cobb: In your underwear. You have giants in your underwear. Like mom!

Me: What?? Giants?

Cobb: Me and Andy and Dad have penis in our pants. You and mom have giants.

Me: Oooooooooh... Yes, I have a vagina in my pants, like your mom.

Cobb: It's a store!

Me: Whaaaat????

Cobb: Our store is a giant!

Me: ................................... Oh. Yes. The grocery story we go to is called Giant. 

Cobb: We go to Giant today?!?!?!
