"Hey ... have you guys seen Kip? I was just at the mailbox and it was bursting at the seams with stuff ..."
"Nope. Funny ... not like him to leave the mail unattended ..."
"You know, come to think of it, I haven't seen him since last Thursday ..."
"Last Wednesday now that you mention it ... when we sent him on that mission during all that Petit monkey business."
Rut roh. Where was Kip, our trusty mail boy?
