Eurovision is back this weekend (Saturday May 14), with Italy playing host.Once dubbed by its much-missed late presenter Terry Wogan as an excuse to, "Have a good sneer at Johnny Foreigner and chuck things at the telly," there's no denying that the annual continental kitsch fest has, during the course of its 66-year history, excelled in dividing its audience.But, whether its return in 2022 presents an excuse to throw a lederhosen and Liebfraumilch party or is simply the ideal time to colour compartmentalise your sock drawer, you cant deny it's had some must-see moments over the years.From bearded ladies and gobbling glove puppets to toppling despots and drug-fuelled scandals, here are some of the craziest which have hit our screens.Eurovision entries have sparked a lot of things over the years, not least the overwhelming urge to grab your coat and head for the pub.But few will beat Portugal’s entry at the 1974 contest which actually signalled a political uprising when it was broadcast on the radio.The ballad E Depois do Adeus by singer Paulo de Carvalho acted as a prompt for the country's rebel generals to rally their troops against the authoritarian regime of the time.The coup became known as the Carnation Revolution, so called because protestors took to the streets to place flowers into the muzzles of soldiers' rifles.The lead singer of this Italian rock band, which won the contest in 2021, was suspected by some viewers of snorting cocaine during the grand finals.Damiano David appeared to have been caught on camera at one point hunched over a table and making a low sweeping motion with his head.
