Our reading
An editorial interpretation.
The comparison imagines the unpleasant feeling of bare feet in a field after cows have relieved themselves. Its indirect wording makes the gross detail part of the joke. The follow-up challenges the listeners' familiarity with the expression, drawing attention to the comparison itself.
