Yes I have, the much repeated and slo-moed clip is from the NATO conference. The world leaders helping him reported he had a back problem (caused by siatica) not that he was drunk.
// Jean-Claude Juncker is recovering from an attack of sciatica, his chief spokesman said Friday, as questions mounted about the European Commission president's health following a video that showed him unable to walk without assistance at a NATO leaders' event on Wednesday.
Juncker's spokesman, Margaritis Schinas, on Friday publicly thanked Dutch Prime Minister Mark Rutte and Portuguese Prime Minister António Costa on Juncker's behalf for assisting him at the dinner.
Rutte, who was one of several leaders to assist Juncker at the dinner, told Dutch media that the president had a back problem. //
