Sleeping on the Mia-ton

I was giving Mia a hard time.  I was saying I was going to sleep with her.  She laughs and says no.  She will either say I am sleeping on the bunk bed or the futon.  Last night, I said I was going to sleep on the Mia-ton.  She laughed and said "I'm keeping the bed.  You can sleep on the futon."
