US President Barack Obama's heavily armoured limousine is known as "The Beast" and for good reason: it's designed to be as tough as a tank and about as heavy.
Too heavy, as it turned out, to drive out of the US Embassy in Dublin without getting stuck.
The ultra-modified Cadillac sedan, also dubbed Cadillac One, thudded to a hefty halt on an exit ramp as the president and first lady were leaving a lunch at the embassy.
Unable to budge a vehicle reputed to have 13cm-thick armour, Secret Service agents drove a minivan in front of it to block the public's view.
After about five minutes, Obama and his wife, Michelle, were transferred to a backup sports utility vehicle to be driven to his helicopter, Marine One, for the flight to Moneygall.
