On his program Tuesday, MSNBC host Chris Matthews called former Vice President Dick Cheney a "troll."

"Well does he ever stop?" Matthews opined. "He's crawled troll-like out from under his bridge to say that President Obama is projecting weakness to our enemies."

"He is really tough," Matthews added later. "I compare him to the troll that comes out from under the bridge and bites the ankle..."

Matthews, if you remember, tried to interdict Democratic Rep. Alan Grayson, who recently likened Vice President Cheney to a "vampire" on his program and said Cheney had blood "dripping from his teeth."

Apparently the veteran newsanchor doesn't think Grayson is too far off. On Tuesday's program, he called Cheney a troll -- twice.

Matthews also called Cheney a "troll under the bridge" in May.
