"Four guys were driving cross..." joke

Four guys were driving cross country together-one from Idaho, one from Iowa,
one from Florida and the last one from New York.
A bit down the road the man from Idaho starts to pull potatoes from his bag
and begins throwing them out the window.
The man from Iowa turns to him and asks "What the hell are you doing?". The
man from Idaho says, "Man, we have SO MANY of these damned things in Idaho,
they're laying on the ground - I'm sick of looking at them!!!"
A few miles down the road, the man from Iowa begins pulling husks of corn
from his bag and throwing them out the window.
The man from Florida asks "What are you doing that for?". The man from Iowa
replies, "Man, we have so many of these damned things in Iowa that I am SICK
of looking at them!!"
Inspired by the others, the man from Florida opens the car door and pushes
the New Yorker out!
