What happens if I push this button???

I was attending a Tourism and Travel life one-year course and my class visited a cruise liner = Birka Cruise. We were shown around in the ship by a guide and when we came to the dance floor and saw all those crystal balls and curtains... I could not help myself. I disappeared behind the curtains as I was curious of what was hiding behind the curtains....I found some sort of music system and I could not help myself and I pushed some buttons and suddenly when all my class was on the dance floor with the the cruise ships guide. Suddenly lamps starts to flash and some romantic soothing music starts to play...ups....

The guide comes running behind the curtain and finds me and he gives me a funny look.
My classmates then gave me a nickname: Little Tinker = Lilla Pillan.
