Hat Thief

Here's something amusing from school today:
N (to G, his "special friend"): You've taken my hat like thirty times today!
G: No I haven't! Only five.
J: Well, five times six is thirty!
C: Where'd you get six?!
(My thoughts exactly, as I tried to pretend that my giggles came from the work I was reading.)
J (mumbling, looking confused): I don't know. (His face clears.) She stole it six times yesterday, I think.
Truly, my students' logic astounds me. :)
