There is great wisdom in your joke. We have a web form builder service. (Jotform) We serve 3 million forms and process hundreds of thousands of submissions daily. Every form pretty much has an email question and most people enable validation feature. We first started with a very very smart and long email validation check that was going to be perfect. Every time users reported a case where our regular expression didn't envision we had to reduce it. During the years we had to change it so many times, I am pretty sure we have left with something like this: Does it have an @? Does it have a period? Great! You are validated!
