There Once Was a Cowpoke Who Swallowed an Ant by Helen Ketteman

A delightful comedy, similar to the classic, I Know an Old Lady Who Swallowed a Fly, but in this case..... There once was a cowpoke who swallowed an ant, a firey thing with a Texas-sized sting. The cowpoke swallows a snake, a boar, and much more all in his effort to rid himself of that pesky ant!
