WEEI is a haven for moron callers, they not only welcome them but cherish them. Especially the afternoon show. I guess they get their kicks from taking morons onto the show then proving they know more than them. It's pretty reminiscent of Cartman trying to win at the Special Olympics. It's not pervasive to all sports radio talk - 98.5 with Felger & Mazz at least make an attempt to bring decent callers on.
It's worthy of note that the day Chris Price was on EEI was probably the best string of callers I've heard on that show - so I'm guessing the hosts have some control over content and the callers.
