most intellectual joke Two scientists walk into a bar. The first scientist says , ""I'll have some H2O"". The second scientist says, ""I'll have a glass of water,too. By the way, why did you say H2O? Like, know it's a chemical formula for water and all, but it's the end of the day and there's really no need to intentionally over-complicate things like that in a situation outside of work"" The first scientist stares at his drink, angry that his assassination plot has failed.
