The Concrete Mixer recipe

If you are ever at a party or at a bar and there is some arrogant guy tell him you have a drink for him to try. Because he will definitely do it. You make the drink and tell him to gargle it in his mouth the chemical reaction between the Bailey's cream in the lemon juice will, within seconds, turn into a chunky cottage cheese like substance. The expression on his face will tell it all. And if he spits it out then he looks like an idiot so he is forced to swallow it.
