Favourite Petty Eurovision drama?

This whole Makra lyric change situation dominating recent ESC discourse is my annual reminder that Euro season is about to kick up a gear.

Let's be honest.... It's not that deep. But I'm living for the drama it's creating (to a certain extent...)

What are your favourite minor controversies down the years? Stuff that was way overblown and ultimately forgotten about after the fact.

I know most answers will be from recent years (thanks Social Media) but the more obscure the better...
