ghost, König, soap and you were drunk and sing some karaoke. One of them came to the good idea to play Katy perry - California girls, you were enjoying the show while they both sing

Ghost “California girls are unforgettable!”

König “Daisy dukes, Bikinis on top”

you were wondering were soap went and in the middle of the song, he kicked down the door with an bagpipes and begins to play on it
