Whenever President Obama visits a foreign country, one of the first things newspaper editors do is go through the startling statistics of the president's car. With five-inch-thick windows, eight-inch-thick doors and a footmat woven from Kevlar, it is no wonder the car is nicknamed "The Beast".
Unfortunately, while it may be bulletproof, it is not speed-bump-proof, as the video below shows.
As the car leaves the US embassy in Dublin, the president's Cadillac gets stuck on a minor speed bump. For six minutes. The mighty Beast was beaten.
What will the ramifications of this be? Probably none, but it's never good for politicians to look foolish on camera, even if it isn't their fault. Just ask Neil Kinnock.
