Chopped Liver

hiya, what can I do for you today?
I was going to invite you out for dinner tonight.
Oh, nice.. that sounds nice.
I'm going to Mum's for dinner.
You're inviting me to dinner with your mother?
Well, *laughs* no.
So, you're calling me to tell me you were going to invite me out to dinner but now you're not?
Ah, yeh.
She has lambchops!
