What?

" Why did the chicken cross the road?"
"What?"
" I said.."
"I know what you said, but this is worse than yesterday. This isn't a chicken either."
" I know that but.."
" Never mind but, get your facts straight. This is even a bigger bird than the geeses yesterday. This is a freaking swan."
" Okay, okay. Why did the swan cross the road?"
"It isn't crossing the road, it is crossing the river."
" I know, I know."
" So why is it walking across the bridge instead of swimming or flying?"
" Oh, so you are telling the joke now?"
" "What?"
" Forget it"
