Summer is rotting Kira's brain

Kira: It would be cool if you could unscrew your arms and take them off.  

Mitch:  Why would you want to take your arms off?

Kira: Because then you could take them off and slap people with them!

Mitch:  What would you hold your unscrewed arms with?

Kira: .........Oh.  I never thought of that.
