The poops are fighting

Sheesh. Everything is about poop. And bums. It's all day, every day with these two. Especially Gavin.

Summer in the bath, Gavin on the toilet.
Gavin: ERG! Uhhhhhh!!!!
Me: Er...you ok there?
Gavin: Yeah, the poop is just fighting in my bum
Me: Your poop is what? Stuck in your bum?
Gavin: No it's FIGHTING. The poops are FIGHTING.
Me: uh....
Gavin: Poops are kind of alive and dey fight sometimes
Me: Is that right? Where did you hear that?
Gavin: Tasha told me.....Mom, you didn't KNOW dat?
Me: Nope
Gavin: Yeah Tasha told me and Tanya told Tasha (Tanya is Tasha's friend and frequent visitor to daycare...also known as ANYA!)
Me: ok then

Bath continues, pooping continues.

Gavin: Mom, how come we don't just poop on the ground like animals and bugs?
Me: Well because if people did that there would be poop all over the place and it would be very stinky outside
Gavin: Well but people could just poop on the road and then just cars could drive on it.
Summer (in the bath): Look Mummy! BUM!
SIGH.
