Last Minute Packing

(And no, I didn't wait 'til the last minute.  Except some stuff has to be done last minute, like the cold stuff in the cooler.)

Isaac: Oh boy! We're goin' somewhere! Here, I'll help you pack.

Me: Thanks but I don't need any help. I got it covered.

Isaac: OK, then I'll just supervise.

Me: OK but... could you supervise without having your nose up my butt?

Isaac (looking confused): What kind of supervisor would I be then?
