You're talking about the old Casey and his brother Commercials that ran on [as] when tom goes the mayor was out and awesome was coming out.

If you didn't care what happened to me,
and I didn't care for you,
we would zig zag our way through the boredom and pain,
occasionally glancing up through the rain
wondering which of the buggers to blame
and watching for pigs on the wing.
