I've actually done like 50% of those...me and a group of friends went in picked up a football, started throwing it back and forth and within a minute (literally) we were kicked out.

Another time we decided to have one of us act retarded (literally) and start walking through the aisles with the most people stealing his hat and mocking him. It was fucking awesome.

I suggest going around yelling "butt plugs" and see how many different reactions you get.
