Parent Body Puns

So I treated myself to some new books yesterday from a small local place near me, I decided to stop off at the parents on the way home and the mother had her face in the book bag before I new what was going on.

I'm showing her what I've bought and when opening one of them, I find a small maggot like creature splattered inside one of the covers! The remains of its body on one side, a goopy mess on the other. At this point the father walks past, peers over my shoulder & says 'you know what that is don't you?'. No I replied, thinking I'm going to get some to quality useless dad knowledge laid upon me........'A bookworm' he states! And fully committed to his delivery, walks clear through the kitchen and out to his shed without even a glance back.
