Limbaugh can officially withdraw the “grudging respect” he afforded Dingy for not turning his brother in. That was the part of the story that was incongruent anyway.
The whole Limbaugh skit was a parody of Reid's lie about Romney's "tax evasion" on the Senate floor. He even used much of the same language Reid used: "reliable source". Remember, Rush rarely tells you when he's using parody. That's part of his shtick.
