Thats a joke son....

I say, I say , I'm just sucking air son-Senator Claghorn

Wiki:

"Senator Beauregard Claghorn was a popular radio character on the "Allen's Alley" segment of The Fred Allen Show beginning in 1945. Succeeding the vaguely similar but not nearly as popular Senator Bloat from the earliest "Allen's Alley" routines, Senator Claghorn---portrayed by Allen's announcer, Kenny Delmar---was a blustery Southern politician whose home was usually the first at which Allen would knock. Claghorn would typically answer the door with, "Somebody, ah say, somebody knocked! Claghorn's the name, Senator Claghorn, that is. I'm from the south."

Claghorn had an unshakable obsession with the South, and would proudly voice his disdain for the north in humorous ways. For instance, the Senator refused to ever wear a "Union suit", or to drive through the Lincoln Tunnel when he visited New York for example, or claim to drink only out of Dixie cups. The Senator even rebuked Allen for saying the word "no" in his presence, saying "N-O.. That's North abbreviated!!"
When Allen was finally able to get a word in edgewise on the Senator, he would ask him a topical question, to which Claghorn would respond with a rapid stream of talk, shouting, repetition, and punnery. After a quip, the senator would laugh uproariously, and utter one of his two catchphrases: "That's a joke, son!" or "Pay attention now, boy!"

That's not a chicken-thats just a loudmouthed schnook-Foghorn Leghorn

Foghorn Leghorn is the name of a character appearing in numerous Warner Brothers animated cartoons, especially Looney Tunes. He is an obnoxious, lazy, and large adult rooster with a and very familiar Southern accent..

Foghorn's voice was created by actor Mel Blanc, patterned after the character of Senator Claghorn. Leghorn used a number of Claghorn's catch phrases, like "That's a joke... I say, that's a joke, son." The references to Claghorn were obvious to much of the audience when the Foghorn Leghorn cartoons first premiered, they have since become dated and obvious at the time are know unknown...
