Az and me stumbled /fell/ gatecrashed/ forced our way into/ was forced (can't remember which) in to a wedding reception/ birthday party/ Christmas party/ Barmitzvah/Hanukka celebration (can't remember which) last night where everyone was dressed as Spiderman/ Batman/ Iron Man/SuperGirl/ Superman/Captain America (can't remember which) just as the cake was presented on stage to the happy couple/ birthday girl/ birthday boy/ gay couple/ employee of the year/ salesman/ saleswoman of the year (can't remember which) and this was playing.
It sounded brilliant.
