How to anger an entire bowling alley:
1) Go to bowling alley with family
2) Put screamo on jukebox
3) Try to mosh to screamo with goth-dressed sister
4) Glare at people when they turn the volume down during the screamo
5) Put on opera
6) Sing and act along to opera/musical
7) Glare at people when they put normal music back on after opera
8) Put on line-dances
9) Dance to line-dances
10) Glare at people to continue the pattern and because they laughed at your line-dancing

And voila! You've got an entire bowling alley worth of people disgusted at your music choice!
:D
