The commercial is likely in French.
It features an animated character with a chin resembling balls.
There's a scene with a man on a toilet reading a newspaper, and the animated character appears outside the window singing before shoving his head through the glass. at the end of the commercial he rips off his shirt and is wielding a sword, lightning strikes etc, its clearly for erectile medication.
much appreciated, song is stuck in my head, infuriating to google
