Radio endless Ha Ha HA

have come to a point where I cannot stand listening to the local radio show in the mornings anymore .There is a particular host who has to comment on each and every subject .Such a damn know it all . If that's not bad enough , everything that comes out of anybody's mouth is followed by this incessant Hah ,Hah ,Hah Ha, Ha ,Ha ,Ha .I just can't take it anymore !
