That Joke isn't funny any more

" Why did the chicken cross the road?"
" That's not a chicken, that is a goose."
" What?"
" I mean it isn't even one goose, there are 2."
"Yes, but.."
" Come on you have to do it right."
" Look It's just a joke."
" I bet they didnt even cross the road, I bey they were at that side all the time."
" Stop!"
" Sorry, go on."
" No it doesnt matter, that joke isn't funny any more."
