Hungry?

HS: I'm sooo hungry! I had five cookies yesterday, I'm never usually hungry but now all I want to do is eat... maybe I'm pregnant?
EM: Or you have worms?
HS: What?!
EM: That's what my Mum always used to say to me if I had a lot to eat, 'Have you got worms?!'
(Later)
HS: OI! Have you been telling everyone I have worms?
EM: I told people that you either were pregnant or had worms...
