The character of Foghorn Leghorn was directly inspired by the
popular character of Senator Claghorn who was a blustering and
bombastic Southern politician (played by Kenny Delmar who was a
regular character on the Fred Allen radio show) . The rooster
adopted many of Claghorn's catch phrases, such as "That's a joke,
ah say, that's a joke, son." Delmar had based the character of
Claghorn upon a Texas rancher who was fond of using the phrase
.
