Big teeth and attack dogs go together like Hitler and his moustache, which explains why Donald Trump has chosen Rudy Giuliani for that unenviable role.

A pretty sight they are not, but the former New York mayor’s enormous choppers take a life of their own when good old Rudy, all clenched fists and beady eyes, goes around hysterically barking an incoherent message of hate supposed to help his no less incoherent and hateful boss win the Presidency.

Probably few people remember what Giuliani said at the Republican National Convention, but his 15-minutes of creepy demeanor and out of control yelling are truly --and unfortunately --unforgettable.

They were weird enough to prompt Washington Post editorial writers ask last Wednesday half in jest: “Is Rudy Giuliani okay?”

“It was notable that when he said Donald Trump loves ‘all people, from the top to the bottom,’ Mr. Giuliani animatedly gestured toward his knees as he said ‘top,’ and above his head as he said ‘bottom,’” the Post wrote. “Also, why did he say that he and his wife, Judith, have been friends with Mr. Trump for 30 years, though he met his wife in 1999, only 17 years ago?”

Why indeed? Oh, Rudy, Rudy, you need help. One only has to see his manic smile to realize he is not well. And then there was his amnesia about –listen to this‐‐ 9‐11.

“Under those eight years before Obama came along, we didn’t have any successful radical Islamic terrorist attack in the United States,” Giuliani said in his weirdly frenetic manner while introducing Trump and Pence at a campaign rally in Ohio. “They all started when Clinton and Obama got into office.”

Yes, “America’s mayor” forgot all about the worst terrorist attack ever in the U.S. in 2001, when he was the main man at New York’s City Hall and George W. Bush lived in the White House.

Yet strangely enough, for 15 years he has remembered the tragedy well enough to exploit it shamelessly and relentlessly for personal gain.

As a Washington Post reader commented, “He (Giuliani), like his hatchet man Bernard ‘Big Bad’ Kerik, continuously posed and preened for TV after the attack. Both prospered‐ Kerik illegally, and Rudolph via his BS worldwide security company.”

Kerik, of course, was the former New York police commissioner who was once Giuliani’s driver and right‐hand man. Sentenced to four years in prison (he served three) for tax evasion and lying to White House officials, during the Giuliani administration heyday Kerik, now a felon, was even considered by Bush to head the Department of Homeland Security.

For all his frantic talk about “making America safe,” the company he keeps speak volumes about Giuliani’s ‐‐ and his boss’—character: Neither can be trusted even to walk the dog.

After the Republican nominee is chased out of public life in the coming election, Giuliani and his enormous teeth are bound to vanish, disappear, go away, hopefully for a long, long time. I don’t know about you, but me, well, I can’t wait.
