Boss 'er 'er

Ty and I had the following conversation the other night:
Ty: Dad can I bring my dinosaur in the bathtub?
Me: No, the dinosaur has batteries, it would ruin it.
Ty: Well I'm going to ask Mom then.
Me: You don't need to ask Mom, I already told you no.
Ty: Yea but Mom's the boss.
Me: I'm your boss too.
Ty: Well she's the boss 'er 'er.
Me: Laughter... It's pretty bad when even your 5-year old son recognizes that Mom is THE boss.
