3 Communists walk into a bar...
one orders a $15 mixed drink, one a $10 Martini, and the other a $6 beer. When the bill comes, based on their mantra, they're forced to split the bill equally.
Next week, the three, once again, return to the bar, but this time, they all ask for separate checks, so the bartender asks them why they aren’t splitting the bill equally, since in communism, everyone pays the same fair share. The three communists reluctantly agree and once again split the check equally.
The following week, the three communists return, but with a mob of devoted followers, and protest the bartender to change the prices of all their drinks to the cheapest drink on the menu.
In fear of his business being vandalized or burned, the bartender agrees. So the following week all the communists come in and enjoy their $6, equally priced drinks and celebrate the success of communism.
The Communists continue this for several more weeks, until one Friday they return to the bar, but find it closed with a sign out front stating that the bar is out of business. Oops...
